I made some tests and conclusion is that OpenLiteSpeed (whatever version) has a bug which makes the load 10x more than normal. Tried all version like 1.4.48, 1.5.2, 1.5.3. For sure this issue is present in CL+DA+OLS environment. I don't know if non-CL is affected or not. According to zEIter it doesnt seem to be an issue.
1.5.3 had an improvement, but still not close to "normal"
... I installed the enterprise trial version, and it dropped immediately. So problem can be isolated to OpenLiteSpeed.
I am in contact with OpenLiteSpeed guys and DirectAdmin team as well. OLS team will have a look on monday.
Nothing can beat litespeed in performance. Spend weeks on making benchmarks, and litespeed win (no difference on OpenLiteSpeed and LiteSpeed Enterprise performance)
I know this thread is old but I would like to know if the problem is fixed?
I'm considering using DA on a shared hosting server and I would like to use OLS for performance
