[p4] Suggestions for migrating from AIX to ???

[Robert Cowham]

You need to be careful how you build/configure your Linux box.

ICManage for example provide high performance/availability boxes and have
some very satisfied high end clients.

Google presented at the European conference on their configuration which has
3,000 engineers against a single Linux box...

As to Solaris, I have can confirm performance - recently been involved in an
evaluation where their Sparc based boxes performed significantly worse than
x86 for activities such as check-pointing which are single threaded (e.g.
4-5 hours vs 1.5 hours on a fairly large repository).

Do a full evaluation!
