PHP Comet? Best Server for heavy concurrency?
i am currently developing a PHP application i implemented a COMET(Long Polling) mechanism.

I heard that Apache is not the best solution for high/massive concurrency and i expect to have thousands of concurrents users at the same time waiting in a loop for new data.

My only constraint here is that i need to use PHP.

What would be the best alternative for maximum concurrency?

Thanks in advance!
