I think I need to clarify a bit. I'm wondering why arc size is staying so low, when i have 10 nfs clients and about 75 smb clients accessing the store via resharing (on one of the 10 linux nfs clients) of the zfs/nfs export. Or is it normal for the arc target and arc size to match? Of note, I didn't see these performance issues until the box had been up for about a week, probably enough time for weekly (roughly) windows reboots and profile syncs across multiple clients to force the arc to fill.
I have read through and follow the advice on the tuning guide, but still see Windows users with roaming profiles getting very slow profile syncs. This makes me think that zfs isn't handling the random i/o generated by a profile sync very well. Well, at least that's what I'm thinking when I see an arc size of 1G, there is at least another free gig of memory, and the clients syncing more than a gig of data fairly often. I will return to studying the tuning guide, though, to make sure I've not missed some key bit. It's not unlikely that I'm missing something fundamental about how zfs should behave in this scenario. cheers, Blake -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
