Re: [squid-users] Slow internet navigation squid vs blue coat

The analysis was made using firebug from different browsers, using
different proxyes/
direct access; with the "problematic" proxy, what I can see is an high
"waiting" time, indicating that the header's page response is high.
Therefore in cache.log i see many
local=xxxxxx:yyyy remote=yyyyyy:zzzzzz FD xxxx flags=1: read/write
failure: (110) Connection timed out
local=xxxxxx:yyyy remote=yyyyyy:zzzzzz FD xxxx flags=1: read/write
failure: (32) Broken pipe
WARNING: Closing client connection due to lifetime timeout

How could I test network related problems such as:
Imix traffic limit
Delay
Bandwidth
....?
