RE: [squid-users] design, wccp, hardware recommendations

The trick for support the thousand of user must be increasing the
ip_conntrack parameter of iptables and increase the max memory object size
in squid.conf

I had test with my DL380 G4 memory 4 GB dual XEON 3.2GHz load test with
webpolymix-4 the box can support with 10,000 concurrent ip client and
throughput increase that 300 MB/Sec (not Mbit/Sec)

My OS is Ubuntu 7.04 standard kernel and tuning sysctl.conf with web100
style.

I'm not use WCCP because it has many problem and difficult to troubleshoot
hello message and GRE but I had use the Foundry ServerIron for HQ and Policy
routing on Cisco because policy routing consume the router processor minimal
than WCCP process

Good luck

Subject: [squid-users] design, wccp, hardware recommendations

Hello,

I would like to implement a couple of squid caching boxes to our network.

These are my current requirements:
-needs to be transparent
-needs to have a failsafe in case of caching server problems
 -should use wccp
-should be able to take it down at anytime with out interruption

This what I currently have in place:
-The network is divided up into two sides. About 400 users on one
side and 600 users on the other side.
-Each side will have one squid cache to start.
-Each side will have a cisco 2801 router with a dedicated fastethernet
port for the caching server.

So my questions are:
-Which documentation for squid and wccp with transparent proxying
would you recommend?
-Which server operating system would you recommend. (Currently debian
is the only one that works with the scsi card that I have in the
server).
-For this amount of users what size of server would you recommend? (If
I have to guess I would say that up to have of the users could be
using the internet at the same time. Average during the day would
probably 1/4 of the users at one time. So around 150 users one
caching server and 100 users on the other caching server.

Any other recommendations are welcome!

Thanks,
Dan
