Please be careful when applying this patch, I think the server hog should be investigated?!
This is rubbish. Applying this patch means to make only the changes I did in revision 2303, and if you follow the "text changed" link in the URL I posted above, you'll see that the change was in two lines which in no possible way can affect the server load. However, you grabbed PivotX Latest (after my recommendation!) which contains many other changes ...
I'm not questioning the fact that using PivotX Latest might have given you problems with server load. It seems I might have had the same problem myself when upgrading one of my servers. We are looking at it.
I downgraded to earlier version (unfortunately losing the wzup and pivote count)
Why on earth did you loose those extensions? You can just copy the folders.
Addition: the problem seemed to start when I installed and tried Google Chrome.
Thx for the info, but you can relax - a specific browser can't cause higher server load. What can happen some times is that a web application can cause high load on the computer running the browser.
