Hello,
I ran three benchmarks, dbench, bonnie++ and AIM. Dbench and Bonnie++ works fine. AIM I failed several times for OGFS with disk_src. But later I changed the operation directory to another directory and I never get that failure again. I think some block/sector in my disk might be broken.
test machines: 4 processors intel Xeon 1.8G , 1G memory, Qlogic qla2300 fibre channel 256 GB shared disk
test version: cvs version as 1pm Sep. 12 2003
I ran benchmarks for both ogfs and ext3 for comparison (ext3 is created in same type of disk). Performace drop in dbench and bonnie++ varies from more than 50% to less than 10% while in AIM most data are pretty close.
