Keep-Alive Help


New Member
Hi All,

I am new to OpenLiteSpeed and I am working on setting it up to migrate my WordPress site over. I am testing a dev version of my site on litespeed now. One of the plugins is using admin-ajax.php and I noticed longer load times than they were on my old apache server. I noticed in the headers there is no Connection: Keep Alive. Looking through my OLS server and vhost config it appears keep alive time out is set. Am I overlooking something obvious? Below are the headers that are listed. Any help is greatly appreciated.

Response Headers:

Keep-alive may not help in this case, you might want to improve your PHP performance. For the WordPress case, you may be able to take some advantage of LSCWP to bypass the wp-config.php trick, which may save you 0.1 or 0.2 seconds.
