No.  I had taken the XFS code from 2.4.9-6SGI-XFS1.0.2 and the XFS CVS updates
and merged it with RH 2.4.9.-21 and built with gcc3-3.0.1-3.    I was still 
working some issues when I saw this announcement yesterday.   

My hacked code would have 98% of memory allocated to cache within 3 minutes 
of starting the test. (Beyond this point it was hard-hats only and falling 
machine parts)

-31XFS1.1-pre2 running the same test has the cache somewhere between 25% to 
75% of physical memory, depending on where the testsuite is in its cycle.

So far I tested 70 drives active where total active open files = 50% of 
physical memory (16G)  (Test ran about 7hours with no errors or data 
corruption before I stopped it.)  IO stats showed numbers ext2 can only dream 

Currently testing 70 drives active where total active open files = 3x 
physical memory.  Has been running 5hours with no lock-ups, errors or data 
corruption and the 32 copies of setiathome are still making good progress and 
the IO stats are literally 100x better that I ever got with ext2!!!

Time to hand over the the benchmark guys!!!
