Since we installed vbSEO on our site, the load on our server increased a lot. We were using one big server with Apache 2.2.9 + PHP 5.2.6 + XCache 1.2.2, and now we use two servers with Lighttpd + PHP + XCache.
I would like to know if we can have less load by using :
- APC instead of XCache
- eAccelerator instead of XCache
- Zend Platform
Do people have experience switching to one of those three instead of XCache and getting performance improvement with vbSEO ?
