Anyone handling more than 3 million HTTP requests a day ? :-)

In the past few months Squid was tried out on one of the cache
machines. During this period the performance was quite poor with
overheads in excess of 1 second on every connection being introduced
by the squid proxy. This compared to about 0.2 seconds on Netscape V2,
and exceeded our goal of less than 0.8 seconds per connection. Its
behaviour with certain elements of the HTTP protocol was also brought
into question by some users. Also, fatal bug fixes were coming out
quite regularly and the work-load was quite high.

As Neil Smith has recently left HENSA Unix for pastures new, he decided
it would be better to have all the cache machines running the same server
rather than three different ones (Netscape V1, Netscape V2 and Squid).
The Netscape v2 was stable enough to put on all the machines.

At the moment Netscape is coping well with the load put on it,
about 2.8 million requests per day. If you know of a Squid server
successfully handling this kind of load we would be interested to hear
about it.
