Hi, I had tremendous performance issues when migrating from an old server running linux 2.4.x and rrdtool 1.2.y to a new server running linux 2.6.w and rrdtool 1.2.y. (managing 20000 rrd files).
The only plausible cause that I was left with was the kernel handling IOs differently. The upgrade to rrdtool 1.3beta solved my performance issue (reads divided by a lot (10 or more if I remember correctly)). I can only say, if you upgraded from kernel 2.4 to 2.6, try rrdtool 1.3 _______________________________________________ rrd-users mailing list rrd-users@lists.oetiker.ch https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
