I have found that zfs cache is a real bottleneck when you have very large files in the zfs filesystem. I have my virtualbox OSes on a ZFS filesystem and had to limit the cache or system performance would bog down. I added the following to /etc/system to limit the zfs cache. * limit zfs cache to two Gbytes (1000 x 1024 x 1024 convert to hex) set zfs:zfs_arc_max = 0x3E800000 This helped although it would be much better if there was a way to limit the size of files it would cache, ie.. tell zfs not to cache files larger than 100meg <mike> This message posted from opensolaris.org _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
