I'm upgrading from 220.127.116.11 to 1.3.6 and am noticing quite a difference in response.
The live 18.104.22.168 site is http://twomorrows.com and the test 1.3.6 site (with re-design and some additional contribs) is http://new.twomorrows.com
Clicking on a product in a list on 22.214.171.124:
Parse Time: 1.103 - Number of Queries: 327 - Query Time: 0.853954992279
Same in 1.3.6
Parse Time: 3.596 - Number of Queries: 381 - Query Time: 2.666831286
Any thoughts or pointers?
