I have my own virtual server in the cloud, running nginx and APC. On this server I have one wordpress blog using the W3TC-plugin. I've enabled page cache and object cache using APC.
When accessing front page, pages and posts the response from the server comes almost instantly. But when doing a search, the response takes 1 second.
I'm wondering if it is possible to make the response faster.
Using the Debug Queries WP-plugin I've profiled the search sql query and it only takes 0.002 to complete. And according to W3TC most objects are cached. In fact, the Debug Queries plugin give the following report on a search result:
Total query time: 0,01482s for 120 queries. Page generated in 0,00000s, 0,00% PHP, 0,00% MySQL
So it seems as if the page is generated very quick. But the response from the server still takes 1 second to complete.
How can I find out what it is that makes the response is taking long, even though the page is generated quick?
Note: I'm only talking about the response time from the server, not the time that it takes to generate the page in the browser.
Here is a example search result from my site.
