Multiple simultaneous requests and cache generation

Wednesday 17 December 2008 11:18:29 am

Hi all,

Can anyone tell me, or at least give me a hint where to look for the answer:

Whenever <b>cache-block</b> or <b>view-cache</b> are expired or physically cleared, what's eZ approach in generating new ones: will all the simultaneous requests compete in generating cache-blocks or view-cache, or will the first one set some sort of lock, making all other requests wait for it being generated? Or maybe any other approach?

This seems to be performance-wise <b>important for heavy-traffic sites</b>, as many competing requests could kill a server in case of accidental cache clear, for example.

Any comments or clarification on this subject greatly appreciated!

Cheers,
Piotrek
