I have drupal 7 test installation on shared hosting. Caching turned off (I do not want to use caching), cron disabled. According to devel, query execution times on page with 228 queries are approximately 1200ms.(some views blocks with relationships, page displayed using context) Loading time of this page is allways more than 1200ms. It is approximately 3 and more seconds. Due to time to first byte, which I am not able to cut down.
However, I decided to try the same install on virtual host running on debian linux 500mb ram. Devel shows on the same page (228 queries) time 50ms - which is great.
But, accessing time to pages is very inconsistent. Sometimes it is amazingly fast, sometimes it takes 8 seconds of waiting and then page loads. What is interesting - even if page loads after 8 seconds, the query time is allways small according to devel.
This leads me to conclusion, that there must be some bad setting on my linux installation. Can anybody point me to the right direction? Thank you
I am new to virtual servers and I think I am missing here something obvious.
