eaccelerator.cache_dir with vhosts

Question

What is the best solution to store the cach files? One directory for all or explicit directorys for each running vhost? Is there any difference?

Answer 1

Unless you have huge amounts of vhosts, from the performance point of view it should not matter.

From the security point of view the separate directories might be a better option than a single directory, depending on your web server setup. If every vhost does use its own user-id (instead of running everything as Apache user), the separate directories are definitely a better option.

Answer 2

At the risk of being unhelpful, have you considered using APC, instead?
