RE: [PLUG] Hardware question
|
I would like to add that AFTER you install an (Symetric Multi Processor)
SMP kernel you can easily "set afinity" (though I cannot remember how to
actuall force afinity of a process to one processor or the other under
Linux right now) for a process or just let Linux do it automatically for
you. I used to run an old PIII dual board and saw more stability (fewer
lag issues, timeouts, etc. when the first CPU was very busy)when I had
the box doing many different things at once. I would not have a dual
processor box again unless I needed to run a busy LAMP box that was also
my workstation. Simply because in te SOHO environment, my old HP PII333
workstation is way more than I need for a home server. (Truth be told, I
would rather even have a NAS unit but why bother until the workstatoin
dies.)
If your box is only going to be a workstation and not a server that sees
some use as well (mine was the server for my house as well as my
workstation) then a single processor will do fine. RAM in my opinion
will always be a key issue for single processor systems since you can
always change your RAM compliment easily (to a point) but not your
system bus speed without a motherboard and possible processor and Ram
type change.
