I was all ready to write about my frustrations with this problem, but I upgraded to snv_117 last night to fix some iscsi bugs and now it seems that the write throttling is working as described in that blog. If a process starts filling the ARC it is throttled and the data is written nice and constant using just about all the disk bandwidth without freezing the system every 5 seconds. However, with gzip-1 compression the symptoms return, but for my system I think it's because the gzip compression is not multi-threaded? I'm only getting 50% utilization on a dual core system. LZJB seems to work well though. Is anyone aware of any bug fixes since 111b that would have helped to mitigate the freezing with the cache flushes? -John -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
