Hallo performer,
we are having some performance troubles with an alpha server 1000 4/233.
We added 256 MB memory so the machine now got 384 MB over all. Now the
server seems to be a real slow performer. The machine is a DB-Server
(Informix 7.12). I added the vmstat output at the end of this mail. To
me the values for "pin", "zero" and "cow" seem to be pretty high,
specially when you compare it to the situation before upgrading memory!
Any suggestions?
