Thanks mistwang. I am a little bit of a n00b with LS, can you explain to me a little on why you think LiteSpeed internal page cache would give us better results than Varnish?
Our current problem is over time the site becomes unresponsive and it seems to stem because ever other day or so the memory and swap usage end up at pretty much 100%. We have to take a box out of rotation restart LS, clear the eaccelerator cache and then restart varnish or worse, reboot the box entirely to clear the problems. When one box goes the other two end up going down shortly after since they can't handle things by themselves. We are looking to upgrade the memory from 4 to 8Gb but also were considering limiting the number of lsphp processes that spawn.

To give a little further backgroud about the site we [mydailymoment.com] have: 1) a joomla section that get ~150K page views and ~50K uniques and 2) a non-joomla section of our site with ~150K page views and ~10K uniques with both sets of number being daily values so we are a high volume site but the issue doesn't necessarily occur at high traffic times. We have done code review and have been unable to find anything glaring that stands out on that front.
Anyway I'll take any thoughts you have.
Much appreciated,
staiano
