Huge <15sec TTFB - drives me crazy

RE: Huge <15sec TTFB - drives me crazy
Hi,

A couple of thoughts.

1. Cache the HTML document - it is super cachable by the looks of the website - you should be able to serve from cache (e.g. Varnish on a CDN) in circa 200ms.

2. Put APM on your web server (like New Relic) to id the long running code / query on your site.

I didn't change anything to configuration of Apache.

Struggling to identify all day and night long yesterday what is happening..

Do you have an idea or please give a hint?

mysqltunner gave:

Run OPTIMIZE TABLE to defragment tables for better performance
MySQL started within last 24 hours - recommendations may be inaccurate
Enable the slow query log to troubleshoot bad queries
When making adjustments, make tmp_table_size/max_heap_table_size equal
Reduce your SELECT DISTINCT queries without LIMIT clauses
Variables to adjust:
query_cache_size (> 16M)
tmp_table_size (> 16M)
max_heap_table_size (> 16M)

it was a f@cken plugin
