Hi, I agree that it is not file system specific as I was testing against the block device: dd if=/dev/cciss/c0d1 of=/dev/null bs=1024k count=1024
Furthermore, the cciss driver (which this bug is about) will not be used by Linux when running on ESX. Changing the Linux kernel version will not change the cciss driver used by ESX. There are plenty of threads relating to SmartArray controllers' performance when used without BBWC - maybe that is the problem you are seeing? Or you are asking for too many IOPs (especially many small IOs when you application is running) from your disk subsystem.
