I'm running my store on a Magento 18.104.22.168 installation and after installing a new theme it took ~55 seconds to load but with few changes it went down to ~8 seconds(which is still too much).
So i started searching for an answer and i found a post about TTFB. In my case it is around 4.5 sec(which is ... a lot).
Is there something i can do to fix this(at least cut it in half, instead of ~8sec to bring it down to ~4)?
I have a VPS server from Digital Ocean which has:
Ubuntu 14.04.1 LTS Apache/2.4.7 MySQL innodb_version 5.5.41
So far i've done this:
- Edit .htaccess file to activate compression(mod_deflate)
- Activate Cache(and flush them and etc.)
- Catalog to flat category/product
- Merge Css/Js
Magento 22.214.171.124 SKU 45.000
P.S: With the default theme and 45.000 products the store goes pretty smooth(~two seconds to load)
P.S.S: After @Haim recommended AOE Profiler i've managed to open one of the scans. Here it is:
