Re: Recommendation for squid proxy server

[Jose Luis Rodriguez Garcia]

I have installed several squids in the past +10 years ago mainly in
Solaris in some Linux.
For so few users any PC will be enough. (the real number that gives
the real uses is the number of http requests per second). I won't care
about configuration, unless you are using a virtual server. Any pc
with a basic configuration will be enough.

The critical point with squid 2.x (the versions that I installed in
that time) is the I/O performance. I suppose that squid 3.x will be
similar.

Basically for web caching and I have a small ISP, serving wireless clients.

Basically 150+ users but my current bandwidth is limited

I'm thinking in NetBSD with a good pair 1TB hard disk (no SSD now).

Hmm,
not sure if i can help you.

If i understand right, you want to use squid as a caching (or "accelerating") 
proxy? What type of users do you have?

Some years ago we runned a squid on a NetBSD (HP proliant machine) for around 
50 users (while we had SQUID installations on ISP level up to 50k users), but 
much more relevant is the amount of requests per second and bandwidth (most 
users are not "surfing" around the clock...). So if your 150+ users are in a 
typical office, even the peak load is typically not very much...

Within such a setup there are many parameters to be aware and to think about - 
i.e. the amount of RAM, type and size of further storage, squid storage / 
stack policies, networking tweaks on NetBSD and squid byself etc.pp.. - bust 
not at least, it depends from your "application".

From my experience on NetBSD (async) it was the same as on Linux (ext4). It 
usually makes sense  to minimize the amount disk requests which are not 
required and spread thw disk access over many (independent) disk heads / 
spindles (on SSD this is another story...). High rpm disks are a very helpful. 
Try to bring "as much as possible" of most often requested cached stuff into 
the RAM and if you not rely on much caching, avoid disk caching.

There was some features which was only available under Linux at that time 
(i.e. full transparent proxy / tproxy - where the proxy "hides" his own IP 
against the servers/clients).

I remember that we had compiled a NetBSD kernel with a higher (double) amount 
of max users, but not shure if this makes any sense with a current kernel.

I would try it - if you are not rely to such special "kernel" features only 
Linux has.


many thanks.
best regards,


Niels.

Recommendation for squid proxy server

[Francisco Valladolid H.]

Hi folks.

I'm working in a new squid/proxy server for 150+ users in my network.
I need some testing, whenever, maybe someone have experience with squid
performance on NetBSD, basically in the Filesystem and security.

If anyone can comment, please let me know.

Best regards.
