Maximum number of requests (per second) of Squid ???

Dear all,

        Our Top-level Web caching server is processing 800,000 to 1,000,000
requests a day with a maximum of 20 requests per second on a (non-dedicated)
Digital AlphaServer-4000 with Squid v1.1.8.
25% of the requests are TCP requests with 7% HITS and 75% are UDP requests
with a HIT-rate of 5%. Nearly 75% is HTTP and 25% of the traffic (in Bytes)
is FTP traffic. [The number of FTP requests is negligible however the
traffic measured in Bytes is reasonably substantial (25% of the total).

On certain moments however the Squid process seems to be locked up which
can only be solved by a kill/restart of the Squid process..

What components of the system (memory, disk, I/O, network bandwith, CPU)
are restrictively to the maximum number of requests a system can
handle?? And (guessing) what is maximum achievable for squid on say a
Digital AlphaServer-4000 ...

Cheers, Henny
