Most any server, certainly those, can handle far in access of 600.
Unless there's some high CPU in-process application process, this box
should be able to support thousands of concurrent clients.

BUT  whether setting MaxClients to 200 or 2000 or 20000, for Solaris
and some other non-Linux platforms you absolutely must ensure there is
adequate swap space defined before increasing MaxClients, because swap
space is reserved per process based on virtual memory size.

which helps drastically with swap space
