I wonder whether this could be a network issue too?

Try accessing the server on a direct cable link just to see whether the
server is on its knees under the strain, or it is a network bottleneck.
(I hope you have a few LAN ports). I would check that first because no
matter how powerful a server you have, it will all be lost unless the
network flows freely.

Only 300 hits spread over 8-10 hours? That's not much, is
it? Visitors are not downloading tons of GB and clogging the
network are they?

Unless 30-50 hit at the same time on this small server, it shouldn't
cause a 6-10 secs on a local network, should it?

I guess it depends on the server strain at a given time, the
performance distribution. If 80% of the visitors come into the
office at say 9am and hit the server at the same time it would be a
struggle for a PIII 400 MHz, 512MB. If the 6-10 secs is all day long
then something is wrong maybe elsewhere?

You don't need a very powerful machine, but going slightly higher,
you may need a box equivalent to PIII 1GHz with 1GB RAM. Maybe you have
an old one lying around in the company. If not, there are thin clients
the size of a book with those specs which also use only 10-20% of the
electricity of the old desktops, so they save money and are much

You could also try running lighttpd (lighty) instead of Apache.
Especially on low power machines, lighty may help. AFAIK, everything
works with lighty. I am running it locally with pmwiki for testing.

In any case check the site with a statistical viewer like
Webalizer or Analog to see where the peaks are (both Open Source).
