Apache https is slsow
- by raucous12
Hey,
I've set apache up to use SSL with a self signed certificate.
With http (KeepAlive off), I can get over 5000 requests per second. However, with https, I can only get 13 requests per second.
I know there is supposed to be a bit of an overhead, but this seems abnormal. Can anyone suggest how I might go about debugging this.
Here is the ab log for https:
