it does help after a compaction but it seems to compact quite a bit under load so the disk is always very active keeping read performance lower than desirable.
after i get the cluster restarted because of the OOM i can give some numbers. ________________________________________ From: Jonathan Ellis [[email protected]] Sent: Friday, December 18, 2009 2:04 PM To: [email protected] Subject: Re: hard disk size Does "nodeprobe compact" to help w/ read latency?
