The Makefiles are being fixed up so it will just compile via the  
sourceforge site.

If you BFU or build your own package via the opensolaris source, you  
can just pkgadd the SUNWfilebench package.

I will increase the quota as required in the future.

Thanks for the suggestion and the URL for the utility "filebench". I 
will study it and if possible apply it for benchmarking.

However, I am having some problems installing filebench which I 
downloaded from http://sourceforge.net/projects/filebench

I unzipped the filebench-1.0.0.tar.bz2 package in the directory 
filebench which contains the following:

-rw-r--r--   1 76367webservd 216 Jun 20  2005 AUTHORS

-rw-r--r--   1 76367webservd 288 Oct  5 13:23 README


The INSTALL and README files both contain references to 
http://www.solarisinternals.com/wiki/index.php/FileBench

But according to the installation manual, the following 2 commands does 
not seem to be working for my Solaris 10 (i386) box!

# zcat (filebench name).tar.Z |tar xvf -

# pkgadd -d .

Please bear with me here because I am only 1 week old with Solaris!

Also there does not seem to be any filebench packages in blastwave or 
sunfreeware.

I think that I am missing a simple thing here. If possible, please guide 
me. I will really appreciate it.

I will do that.

Thanking you...

No, that looks ok. You can just 'zfs set quota= mypool/cache'
to be bigger in the future if need be.

filebench sounds like it'd be useful for you. It's coming in the next Nevada
release, but since it looks like you're on Solaris 10, take a look at:

Remember to 'zfs set atime=off mypool/cache' -
there's no need for it for squid caches.
