mm.cfg Secrets
*Update: 9 dec 2011*
This article was the very beginning of what became simply the best toolset for debugging and optimizing flash content: TheMiner. Using a few of these hidden features, TheMiner let you analyse memory, performances, DisplayList, loaders and a lot more! If you have a flash application that could benifit some optimization, TheMiner is the right toolset for you!
*end update*
Read the Original Article (contains a lot of comments that might help you)
I knew for a long time now that flash had undocumented features, little part of flash that could help speed up process (like the memory opcodes) or make interaction easy with right click and that kind of things. But I never thought that FlashPlayer would hide data that could help find bugs, or give better knowledge of how flash is interpreted.
As you may know, The mm.cfg files is located in:
- Windows; C:\Documents and Settings\username\mm.cfg
- OSX; /Library/Application Support/Macromedia/mm.cfg
- Linux; home/username/mm.cfg
This file is interpreted when a Flash Player instance launches a SWF and gives indication of what should or shouldn’t be done.
For example, most people use this file to set tracing parameters:
ErrorReportingEnable=1
TraceOutputFileEnable=1
TraceOutputFileName=c:\logs\flashlogs.txt
MaxWarnings=50
Many other options are specified in the Adobe FlashPlayer Admin Guide… but most of is NOT DOCUMENTED!
There is a LOT of thing to talk about and many cutting edge tools to improve your understanding of flash.
So let’s get into it
The Treasure
The complete list of features of mm.cfg is at the end of the post, but first lets talk about what’s most interesting.
I took my favorite 7 features and made detailed explanation with example for each one so here they are:
TraceOutputBuffered = 1|0
This feature is essential to the rest of all the cool features because they output A LOT of lines in the flashlog
This is a very simple features but it change everything. Did you ever had problem tracing to many information and losing half of it in the flashlog?
Well this is a known bug. If you make a loop of 1 000 000 and you trace the iterator, the flashlog will skip thousand of entries and will take 100% of your CPU while writing to disk.
If you set this variable to true, the traces will be buffered and the write to disk will output multiple lines in one access.
Performance? By default (without this feature), I’m able to trace 3600 line in 6 seconds and my CPU is at 100%.
If I turn the features on, I can trace 1 000 000 lines in the same time! And my CPU is not even near 100%.
AS3Verbose = 1|0
This one is totally crazy.
It traces detailed information about SWF ByteCode structure and Runtime parsing of the bytecode!
You don’t need any software… no special framework to bind in your own SWF… just this one flag!

AS3Trace = 1|0
This one is also very useful for debugging
It trace every single call to any function that is being called in the SWF at runtime!
It’s like expending the StackTrace to the full software run time.
If you got a crash hard to find, you can turn this on and you will see ALL the last function executed that leaded to the crash.
You can even see Timer Call and Events callbacks!

AS3StaticProfile = 1|0
This flag enable Just in Time Compiler (NanoJIT) logs.
It gives detailed information on function conversion, bytecode conversion, MIR (machine-dependent intermediate representation) created, memory used and many others.
At the end of execution, it also output a summary of all bytecode processed (For each opcode you have the number of occurrence, relatives importance, etc)

AS3DynamicProfile = 1|0
This one give dynamic information about the opcodes being called and gives statistic for each.
The statistics include count, cycles, %count, %times and CPI
My question is: Having access to the CPI (Cycle per instruction) will we be able to conclude all
fights between what operation is faster that the others? Cycle counts does not lies (on the same platform…)
* Request for Jackson Dunstan: Wanna work on that? 🙂 *
But there is a problem with this one, it crash all the time.
My guess is it can’t process “Flash Object” like Movieclip, Event, and all the other and only support operation valid in tamarin.

LogGPU = 1|0
This enable logging GPU information about current SWF while it runs.
Use GPULogOutputFileName = [path] to specify where to output that log.

PreloadSwf?flashvar1=value&…
This is mainly used by the FlashBuilder Profiler. When you launch a SWF profiling, FlashBuilder add this line to mm.cfg to make it run another SWF before the one you profile.
The default file is: C:/Documents and Settings/{USER}/My Documents/Flex Builder 3/.metadata/.plugins/com.adobe.flash.profiler/ProfilerAgent.swf?host=localhost&port=9999
The profiler agent is a SWF that use the as3 sampling classes to collect information and send them all over a socket connection to FlashBuilder.
FlashBuilder is only interpreting that data received from the SWF
By changing localhost by any other machine name you can connect to a remote FlashBuilder Profiler. On the Remote profiler you need to check the “wait for application” box and then start the local SWF on the other machine.
This one is just crazy powerful: See: One SWF to rule them all! and New visual Profiler

Specifies how the NetStream constructor connects to a server when a value is specified for peerID, the second parameter passed to the constructor.
RTMFPTURNProxy = 1|0
Lets Flash Player make RTMFP connections through the specified TURN server in addition to normal UDP sockets.
ScriptStuckTimeout = X
Lets you specify the time after what the timeout (too much time running a script) exception will popup
SecurityDialogReportingEnable = 1|0
Lets you specify whether the Security dialog should be visible or not.
SuppressDebuggerExceptionDialogs = 1|0
Lets you specify whether the Error dialog should be visible or not.
ThirdPartyStorage
Lets you specify whether third-party SWF files can read and write locally persistent shared objects.
TraceOutputBuffered = 1|0
Specify the flash player to use a buffer before writing to disk. If you had problem when tracing tousands of lines and line were skipped, this solve the thing. It’s also a lot faster (1000000 trace in 7 seconds instead of 3200 trace in 7 sec!)
TraceOutputFileEnable = 1|0
Set TraceOutputFileEnable to 1 to enable the debugger version of Flash Player to write trace messages to the log file.
TraceOutputFileName= [path]
(Before Flash 9) Sets the location of the log file. By default, the debugger version of Flash Player writes error messages to a file named flashlog.txt, located in the same directory in which the mm.cfg file is located.
UseBrokerProcess = 1|0
Lets you specify if you want to use elevated privileges or not (See the FlashPlayer update)
WindowlessDisable = 1|0
Lets you disable Floating Flash (ex: Ads)
Conclusion
This whole thing opens a new playground for hardcore programmer like me.
A lot can be done with this new information:
- Custom Profiling tool using AS3Verbose and AS3Trace modes
- Custom Profiling tool using .dat generated by FlashProfiler
- Automatic Code performance warning using NanoJIT structure analysis
- Guide to performance using CPI (cycle per instruction)
- Mapping of profiler using the PreloadSwf features (instead of localhost put any other host that have a valid profiler)
I didn’t have time to work extensively on each features and I may have interpreted incorrectly certain things.
If it’s the case please tell me and I’ll modify this post. If you do test or benchmark using this post information please post them as comment here and I’ll add the benchmark later in the post.

awesome post mate… Ill be sure to reference from my blog.
Cheers… and great work on the profiler too.
WONDERFUL!!! thanks a lot! I’d like to ask: I can’t get any flash debug player version more than 10.1 (10.3.181.23 is actual now) to work – it plays flash content but doesn’t debug flashlog. I’ve tried many versions but everytime I must return back to 10.1 version that works.
Does anyone know where is the problem? Has anyone same problem?
you can find the latest debug version at http://www.adobe.com/support/flashplayer/downloads.html
the molehill releases are release version only. (exept for the developers in the prerelease program)
Cool. Thanks a lot!
Actually, the mm.cfg is sourced from %HOMEDRIVE%%HOMEPATH%.
This may or may not equal C:\Documents and Settings\username. For domain users with remote home dirs it will typicaly not.
I’m trying to get gpu information out of flash (I want to know if flash is using gpu acceleration or not). My platform is Ubuntu 11.10 x86 with flash debug version 11.1. I enabled LogGPU in mm.cfg but I don’t see any GPU logging. There are logs in ~/.macromedia/Flash_Player/Logs/flashlog.txt but nothing GPU related. DisplayGPUBlend also doesn’t seem to do anything…
Has anyone had any success with LogGPU (on linux)?
I think this mode is only available for “old-gpu-mode” (wmode)
it’s not about molehill (Flash11)
Any other option to know for sure if Flash11 is use HW acceleration (that’s why I wanted to give LogGPU a try) on a specific platform? I found the requirements for Flash 9 (http://blogs.adobe.com/penguinswf/2008/05/flash_uses_the_gpu.html) but they are probably already outdated too…
You can do it by code. At sociodox we could add a little something in TheMiner to test for these thing. Please fill a bug/feature request for that at: http://www.sociodox.com/TheMinerBugBase/
I’ll make sure it’s done soon! Thanks!
Done: http://www.sociodox.com/TheMinerBugBase/view.php?id=20
Thanks for the quick replies!
Much agreed. I learn a little something totally new and complex on sites I come across on http:
//jpauclair.net/mm-cfg-secrets/ regularly. It’s certainly helpful to examine posts from other authors and incorporate certain things from other pages.
I’ve been browsing online more than three hours today, yet I never found any interesting article like yours. It’s pretty worth enough for me.
Personally, if all site owners and bloggers made good content as you did,
the internet will be a lot more useful than ever before.
Hey there exceptional blog! Does running a blog such
as this require a massive amount work? I have absolutely no understanding of coding but I had been hoping to start my own blog soon. Anyway, if you have any ideas
or tips for new blog owners please share. I know
this is off topic but I simply had to ask.
Thanks!
Many of these new creations are about shape and texture
as much as color and style. The Unitron website includes detailed description of
the features and benefits from this product. Wearing an elegant UGG boot with tight jeans
can give you a classy and beautiful look.
So, it is necessary that you plan your shoe budget before buying
one. You should always seek advice from someone who has purchase the original boots before.
A new kind of wire mixed with natural fabrics, like
cotton, provided the perfect adjustment to the
body.
