Thank you very much (Alan and Daniel) for the great advice : in fact,
it's embarassing now to look at the wasted resources over here
(and finally i understand how hosting services can offer such
good deals in the States).
Guess I will turn those Alpha into FreeBSD boxes. (i am hoping that
an old "connection reset by peer" error i used to have with Apache on
AIX no longer exists on FreeBSD.)
Thank you very much once again.
Chas
ps. I also didn't realise that an Alpha 266 or 300 would be slower than
a P133.
