Amos

how little slower?
mean 5000 concurrent connections less or maybe a litle bit slower like
like 200 connections.
Or is it in the disk subsystem?

And what about stability and features like ntlm passthrough auth?

i tested this with squid 3.1 which works perfectly.
But 3.1 latest has no fix for bug 2155 and i get those once in two days.
I know this is fixed in the tree as stated in the bug report.

Any further recommendations for disk / os tuning?

With kind regards

William
