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.
