...0s 0% 208k I found one post like this earlier (by Xin LI), but nobody seemed to have replied... in my current conf, I think my kmem/kmem_max is at 512Mb (not sure though, since I've edited my file yesterday for next reboot), with 2G of system RAM.. Normally I'd run kmem(max) 1G (with arcsize of 512M. currently it is at default), but since I just got back to 2G total mem after some hardware problems I've been runnig at those lows (1G total is kindof tight with zfs..) Well, just wanted to report... The box is not totally dead yet, ie I can still do Ctrl-T on console, but th...

We have a 32 GB RAM server running about 14 zones. There are multiple databases, application servers, web servers, and ftp servers running in the various zones. I understand that using ZFS will increase kernel memory usage, however I am a bit concerned at this point. root at servername:~/zonecfg #mdb -k Loading modules: [ unix krtld genunix specfs dtrace uppc pcplusmp ufs md mpt ip indmux ptm

Would someone "in the know" be willing to write up (preferably blog) definitive definitions/explanations of all the arcstats provided via kstat? I''m struggling with proper interpretation of certain values, namely "p", "memory_throttle_count", and the mru/mfu+ghost hit vs demand/prefetch hit counters. I think I''ve got it figured out, but

Hi all, I have exchanged my Dell R610 in favor of a Sun Fire 4170 M2 which has 32 GB RAM installed. I am running Sol11Expr on this host and I use it to primarily serve Netatalk AFP shares. From day one, I have noticed that the amount of free RAM decereased and along with that decrease the overall performance of ZFS decreased as well. Now, since I am still quite a Solaris newbie, I seem to
