...n roughly the following method: # streaming clients pool load [%] 15 8% 20 11% 40 22% 60 33% 80 44% --- around here txg timeouts start to shorten --- 85 60% 90 70% 95 85% My application does a fair bit of caching and prefetching, so I have zfetch disabled and primarycache set to only metadata. Also, reads happen (on a per client basis) relatively infrequently, so I can easily take it if the pool stops reading for a few seconds and just writes data. The problem is, ZFS starts alternating between reads and writes really quickly, which in turn...

The big problem that I have with non-directio is that buffering delays program execution. When reading/writing files that are many times larger than RAM without directio, it is very apparent that system response drops through the floor- it can take several minutes for an ssh login to prompt for a password. This is true both for UFS and ZFS. Repeat the exercise with directio on UFS and there is no

Hi All, I''ve just built an 8 disk zfs storage box, and I''m in the testing phase before I put it into production. I''ve run into some unusual results, and I was hoping the community could offer some suggestions. I''ve bascially made the switch to Solaris on the promises of ZFS alone (yes I''m that excited about it!), so naturally I''m looking
