I've recently installed a new test site with a Lot of plugins, and I'm working on themes with Upfront. It's all very slow, working on a remote shared host. (For production I'll almost certainly move to a faster private server, sooner if it's too painful, later if I can defer until I'm sure the site is worth it.)
I'd like to know what caching and other optimizations I can apply while I'm doing development, without getting conflicts where I can't see live updates to active changes. There is a lot of advice in forums and blogs about caching and plugins to help improve performance, but rarely mention about this (unwarranted?) concern I have.
A blog isn't normally a highly dynamic environment, so to-the-second updates aren't usually required. But as we use WordPress more as a CMS, including Ajax queries, and as we use live tools like Upfront in editmode, I'm wondering if some of the advice out there might be outdated.
So I'd like to compress and cache as much scripting and styles as possible, since most of that isn't changed too frequently but I suspect this is where most of the pain is found. Is that accurate? And what other areas should be targeted?
Or should I turn on all possible optimizations and let Them decide what's stale and needs to be refreshed?
