I am away until next week now (hopefully no problem will occur until then) I will try reproduce the issue then. I have to say that v28 massively increased write performance over samba, over 3 times than when v14 or v15. How do you disable ZIL with v28? I wanted to test performance in the case I'm trying to qtroubleshoot. Writing our file over samba, V14-v15: 55s V14-v15 zip disabled: 6s V28: 16s.. (with or without separate log drive: SSD Intel X25-m 40GB). Playing with the only zil parameter showing in sysctl, made no difference whatsoever. UFS boot drive: 14s sequential read shows over 280MB/s from that raidz array, similar with writes I started a thread in the freebsd forum: http://forums.freebsd.org/showthread.php?t=20476 And finally, which patch should I try on your site?
