I'm making some testes with pfSense (1.2Beta1), and got something
curious with Squid.
I've enabled the squid package as transparent proxy, allocating 1GB,
24MB as memory cache size and 8KB as maximum object size. All the rest I
left unchanged.
I also had configured traffic shaping using the traffic shaper wizard,
limiting p2p to 512kbps.
After 24 hours testing the p2p shaping I decided to test an http
download of two CD ISO images (simultaneous download). I got a good
download speed of ~50Mbps (the client is directly connected to pfSense,
and the file server is in our IDC), but the CPU of the pfSense machine
got to ~80-90% load. With a quick check, I identified squid as being the
reason for the overload. Here comes the strange part:
When I uninstalled squid, the download speed dropped to ~12-15Mbps. The
CPU load was gone, but for some reason the performance dropped too. I've
double checked the performance test, and the results repeated themselves.
In theory, since I set squid to ignore objects with more than 8KB, it
should not affect neither CPU nor down-speed in this case, but it is,
and in a most curious way. Any ideas?
