I have a network of 4500 sites running. They are all low traffic sites, except one which is about 1000 unique visitors daily. A few others are 50-100/day.
Ok, so I hoped that upgrading from 1.4 to 1.7.1 would reduce server load given some performance improvements.
Attached is a screenshot which shows what server load was like before, and after (the red line). Before load always went up during auto archiving, but dropped at completion. With the upgrade to 1.7.1 load just stays high.
Note that which running the coreupdate script from command line it ran for a while then reported a “Segmentation Fault” error. The upgrade seemed to have run however as everything was working.
Have now reverted back to version 1.4
Anyone else experienced similar issues?
