I think I emailed this to someone once before many months ago, and so this time I'll say it publicly..

When the Second Life client is sitting at the login screen waiting for someone to type their password, it is hitting the filesystem as fast as it possibly can, repeating three operations over and over and over again:

CODE

6:27:44 AM	SecondLife.exe:2524	IRP_MJ_DIRECTORY_CONTROL	C:\Games\SecondLife\	SUCCESS	FileBothDirectoryInformation: dbghelp.dll	
6:27:44 AM	SecondLife.exe:2524	IRP_MJ_CLEANUP	C:\Games\SecondLife\	SUCCESS		
6:27:44 AM	SecondLife.exe:2524	IRP_MJ_CLOSE 	C:\Games\SecondLife\	SUCCESS		
6:27:44 AM	SecondLife.exe:2524	IRP_MJ_DIRECTORY_CONTROL	C:\Games\SecondLife\	SUCCESS	FileBothDirectoryInformation: dbghelp.dll	
6:27:44 AM	SecondLife.exe:2524	IRP_MJ_CLEANUP	C:\Games\SecondLife\	SUCCESS		
6:27:44 AM	SecondLife.exe:2524	IRP_MJ_CLOSE 	C:\Games\SecondLife\	SUCCESS



FileMon reports that these three operations are occurring at a rate of 1,323 times a second, and based on my past experience with FileMon, I can see no reason whatsoever for this activity to be occurring.


What is filemon? It's a Windows debugging tool from http://www.sysinternals.com/ that I use at work to figure out why various programs misbehave when they are run under restrictive Windows security settings. In this case I am wondering why the SL cache accesses are so inefficient. Nobody seems the slightest clue why it's so slow, and so I'm just curious to see what Filemon can show me.

Well, immediately after starting up the SL client I run across this. Perhaps these three endlessly repeating commands are part of the reason SL has performance problems?

Throughout the many programs I've checked with Filemon, it's normal for things to settle down and for a program to sit quietly once it gets to a prompt like this, since there's no reason to be accessing the drive. All drive operations should be done, with no further work to be done until the user starts the login process.

Yet the SL client keeps hitting the filesystem over and over and over and over and over. I paused the capture, cleared the log, and let it sit at the login prompt for five minutes. What happens when I resume the capturing for ten seconds? WHOOOSH, another 13,788 operations blow by.

So all the while I sit here, with the SL client in the background at the login prompt, it is burning up 1300 filesystem operations a second... for nothing.


Even after logging in, it continues to do these three operations over and over. After waiting for the download throughput to drop to nothing and the world is loaded, the client spends the majority of its file accesses doing these same three operations.

I've no idea whether or not these operations serve any purpose after logging in, but the way it acts at the login screen and continues to act after the environment has stopped loading, suggests this is just a rogue hunk of code that should be killed by the coders, since it probably is doing nothing at all but wasting CPU cycles and slowing down the client. (It looks to me like rogue debugger code that escaped from the programmer's lair.)

Here are three seconds of filesystem activity after sim loading has settled down:

Can someone please take a look at the code to see what is doing this? Is it really necessary for the client to be doing these operations continuously?


(And no, my intent for using FileMon in this manner is not at all an attempt to violate the TOS.) :)

Thanks for all the data Scalar! I'm not able to answer this question, but I'll pass it on to development for their perspective.

Thanks for all the data! I'm sorry we didn't get to this issue before.

This is indeed a bug in Second Life, and will be fixed in the next release. I don't know how much actually disk access this causes -- hopefully the file information was sitting in the disk cache.

Sometimes graphics drivers (especially those from ATI) take over the "exception handler", a piece of memory we use to detect crashes and handle them. We therefore try to detect when the exception handler has been overwritten and grab it back. We do this once per frame. Unfortunately, a bug in this process was looking up the location of dbghelp.dll once per frame.

We no longer do this, so Second Life should hit the disk less. The patch will go out with the next release.
