I've a couple of Mediawiki (1.19.1 with Vector Skin) sites on Dreamhost shared hosting and I've found that access trough Firefox is much slower than trough Chrome. For example at this moment, after cleaning the cache in both browsers:
Firefox
- 11.1 seconds for the first page (RecentChanges)
- 7.7 seconds for the second page (Home)
Chrome
- 9.2 seconds for the first page (RecentChanges)
- 3.2 seconds for the second page (Home)
This numbers confirm previous tests, made in 2 different days a few weeks ago. Please note the huge difference for the second page.
An older version of Mediawiki on a different server does not seem to have this problem. Firefox and Chrome have similar results.
I need to know how to make access trough Firefox as fast as trough Chrome, without changing the hosting company/plan, Mediawiki or asking users to change Firefox's defaults.
