let's say I want to improve my application's performances.And I want to use an Opcode cache tool such as APC or eaccelerator and apply variable caching using Memcached. Let's say then I'm a beginner and I have built a working-app using the above specifications.
When I need to publish my site (remote) and I'm looking around for the best "hosting solution" which host-parameters should I care about when it comes to install php extensions such those for my caching tools?Is it even possible to do that using a shared host?
I'm working on a windows environment but I read that Installing such caching tools (or whatever) on Linux server I need to type few commands within a shell..Do this mean host should provide me with a shell window?I'm very confused about this topic.
Hope you can help me out
