Generally yes. If it was on a virtual server, I'd have suggested that another
virtual server on the same host might have been hogging resources - but that's
not an option.
My next suggestion is to look for the gross cause of the slowdown. Performance
Monitor (on Windows) or top / vmstat (on UNIX) and see whether you're short of
memory, CPU or disk bandwidth when the system goes slow. If one of those is
the problem, the next step is to narrow down which process is the memory, CPU
or I/O hog and find out why it only happens at weekends. If you're not short
of any of those, the next step would probably be to look at your database
server and try to work out whether that's somehow causing the slowdown.
