Re: [squid-users] Best OS for Squid?

That may be so. But there is no need to argue which OS is faster based
on the filesystem. In fact, it's silly to argue about it. We know
which OS is faster for Squid. There are tons of benchmarks that tell
us. Not to mention that this same debate happened here on this very
same list less than a year ago.

Soft Updates are really cool, and everyone here thinks very highly of
FreeBSD. But Squid+aufs+ReiserFS on Linux is faster. Sorry. That's
just the way it is. Even with the Linux machine using DiskD, ReiserFS
is faster for Squid workloads. It just is. Perhaps there are ten
filesystem experts who will support your case that Soft Updates are
"superior technology", and maybe they are--but as it is implemented
under FreeBSD, it is not faster for Squid's millions of little tiny files.

There are even better theoretical filesystem solutions than ReiserFS for
Squid workloads, for sure, but none that work today. I'll be happy when
COSS is finished and we can all use an overlaid 'filesystem' that
performs better than anything currently available and performs similarly
on most Squid supported platforms.

All that said, if you prefer FreeBSD that's great, you /can/ get a
reasonably fast Squid by using DiskD and Soft Updates. It will handle
most peoples needs just fine.

Use what you're comfortable with...it will save you time and trouble, in
most cases. The only time it matters is if you're supporting a pretty
large bunch of bandwidth (like 10Mbits+).

But again...This sort of debate doesn't need to keep coming up. The
Squid list isn't the place for OS wars. It accomplishes little when the
debate is already over for the existing filesystems and Squid.
