Re: [squid-users] Slow connections

What does the cachemanager have to say?

Try:

client mgr:info

Check the service times for hits, misses, and DNS lookups at a time when
things are slow.

Check memory usage. Is there any chance Squid is going into swap, even
just a little bit?

Also check browsing from the proxy server itself to make sure there
isn't some weird issue in your network that is affecting the proxy:

lynx http://www.some-problem-site.com

and to check it likewise through the proxy:

client http://www.some-problem-site.com

Is lynx noticeably faster than the client at retrieving the page
(remembering that Lynx is a real browser, client is just a simple HTTP
client with no HTML knowledge--a more accurate test would be to use wget
with and without the proxy to retrieve some set of files a few times and
compare the averages to see if Squid is the problem, or some other
aspect of the proxies network configuration is to blame).
