RE: How many class files do YOU have?
Brook, Well I was curious about your question so i went ahead and took a look at how many class files we have.We also create cfm files on the fly for new accounts etc.On checking we have 25,759 class files in the cfclasses directory.All the suggestions below are accurate.Be sure to set your template cache as high as is reasonable with the memory you have.Also the jvm settings mentioned are very important.These things should all make a huge difference in your performance.

RE: How many class files do YOU have?
I thought Brandon said that with that many class files you would be better off not storing the class files to the HD and compiling them to memory at run time instead?

RE: How many class files do YOU have?
Brook, We don't have the option of compiling them to memory as I think that is only a 6.1 thing.Regarding the template cache size.It is based on the number of files that you think will be in use at one time.In our case not all 24,000 cf files will be used all the time so we set it to some reasonable percentage of those files.75 - 80%.In your case you could probably do all of them with no ill effects.

And another question related to disk usage; what are the guidelines for a paging file and is it needed if you have lots of physical ram? The reason I ask is because I wonder if a fragmented HD, and a page file on that disk might cause problems. Ideally, on a Windows machine, you'd place the pagefile on a separate partition, and you'd set it with a fixed size equal to the recommended size, so that it's always exactly the same size. If you do this during your initial machine configuration, you won't have to worry about pagefile fragmentation.

Re: How many class files do YOU have?
Here's something pretty scary: I've got 4,105 on my localhost, and there's 4,107 on our server.

RE: How many class files do YOU have?
There is a slick utility offered by Sysinternals 'http://www.sysinternals.com/ntw2k/freeware/pagedefrag.shtml' called pagedefrag that does a great job defragmenting your pagefile (if you don't have the luxury of putting it on another disk.I've been using it for a year now on all our windows NT+ class systems, at the worst it doesn't seem to create problems, at the best I think it helps machines start and stop faster. Dave's recommendation of setting the minimum size to the same as the maximum size is mandatory on our systems (one of the first performance setting we make). Also, if you have a lot of memory you can disable paging 'HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management' 'DisablePagingExecutive' to stop the OS from putting peices of itself in swap. Even if you do have a lot of memory many programs will not work unless you have a paging file, I guess even computer programs like to have a place to doodle? -Nate -Original Message- From: Brook Davies [mailto:[EMAIL PROTECTED] Sent: Friday, April 09, 2004 2:25 PM To: CF-Talk Subject: How many class files do YOU have?

Re: How many class files do YOU have?
If you have that many CFM's then the reason you are getting OutOfMemory errors is due to the fact that you are running out of space in the permanent generation of the Java Heap. I won't get into specifics with JVM tuning. I have some info on my blog http://bpurcell.org but to fix this bump up the -XX:MaxPermSize value in your jvm.config to 192 or 256 it should get rid of the problem. Also load testing has found that you can uncheck the value save class files in the admin and still get the same performance without storing the class files to disk. They will be compiled on first hit and loaded into memory. With the slick new compiler in 6.1 it is very efficient, in fact more efficient than having to sort through 6000 class files to load the appropriate file.

Re: How many class files do YOU have?
Brandon, OKay, I set the server to NOT write cache files to disk and deleted all the cache files. I also increased the maxPermSize as suggested. Any reason I should not increase it to 512? I have the 3 gigs of ram on the server. Also,my app writes lots of cfm files to disk, that why I have 6000 class files. Will this still be okay using the on-the-fly-compiler? Should I set the template cache higher than 1024?

Should I set the template cache higher than 1024? Yes, I think you should set it to the number of CFM files you have (or expect to have).
