We are now 6 weeks into production with our cart, and are dealing with some significant performance issues.
The most notable are LONG delays getting to a product detail page, but in general, the site is sluggish, with frequent delays that can run up to a minute or two.
Our standard response when delays are prevalent is to clear cache and restart application, and aside from the long compile-time delay the first time a page is accessed, that seems to help, but within a day or two, performance is again poor.
We moved the site from a shared hosting account to a dedicated virtual server, shortly after implementing, to have better control over configuration. We have just increased available memory to the virtual server from 512mb to 1024mb, and that has helped a little.
Are there any specific configuration recommendations to improve performance? Or are there any performance improvement changes in the development pipeline?
Ours is a small site, with fewer than 200 products, and order traffic is on the order of 10-20 orders per day. This application is the only one implemented on the virtual server, so there is no outside impact to be worried about.
