Do I need to mkinitrd when changing QLogic queue depth?
I'd like to benchmark I/O performance with different QLogic driver queue depth. According to
I need to mkinitrd after I make the changes in /etc/modprobe.conf. Why? I won't change kernel.
This is for both RH 4 and 5. I think I can check the current queue depth by any of the following:
grep "queue depth" /proc/scsi/qla2xxx/* (only found on RH4)
cat /proc/scsi/sg/device_hdr /proc/scsi/sg/devices (the qdepth column)
It looks like RH4 uses 16 and RH5 32.
(In case you ask why, this article
inspires me to do the test.)
