Hi. I noticed that my website lags in many occasions.. taking sometimes up to 6 seconds to load a page.. I asked my hosting support and they said my account is throttled to avoid overloading the CPU. They adviced me to investigate my logs, and specifically "query_time".
I found many Query_time executions exceeding 2 seconds.. sometimes even reaching 8 seconds. I have gathered 82 Query_time entries that exceed 2.5 seconds from the last week and put them all in one log file for easy diagnosis. I wish you'd help me to know what is causing the lag and how can I solve it. I am using WordPress with W3 Total Cache.
The log is attached. Please help me with this as the slowness experience is really driving visitors away !!
