Once again, I'm using squid as an http-accelerator... Squid seems to be capping rate of transfer to around 80 KB/s...I'm doing this transfer locally from one squid box to another via wget. If I do this same transfer using scp, I get around 90 MB/s sustained. I'm also noticing drastic fluctuations in speed when downloading from squid...every once in awhile it will jump up to 300 KB/s, but then fall back down to around 80 KB/s again. I have eliminated the network, hardware and server configuration as potential problems -- I'm 99.8% sure it's squid. Does anyone have any ideas as to why squid is having trouble filling the pipe?
