I haven't noticed this problem myself (and I'm using 5.4 RELEASE), probably because I'm not using SCSI, but I am curious about the patch committal. If I understand right, this patch is not currently committed to the RELENG_5_4 branch, that not being the same as STABLE or CURRENT. Since this is a performance issue that many (like the OP) would consider serious, is there any chance this patch would make it to RELENG_5_4? I ask this purely out of curiosity, not to see whether I (or anyone else) agrees or disagrees with it. :) Thanks!
