Apache with the pre-fork MPM is a set of single threaded processes, with the worker MPM it is a set on multi-threaded processes. The lifetime of each process is configurable, it's possible to configure a new process for every connection (or every http request if keepalive is not enabled) but performance suffers so I think it is normal for each process to handle hundreds, or thousands of requests. The cache code is new but in-memory caching is not, to a certain extent the current code replaced the previous in-memory cache. -- Philip
