There's 86,400 seconds in a day - if you got 8500 hits a day in the main 12
hours of the day (assuming its not a global site here) thats only one hit
every 5 seconds. Unless it was doing something really major with the HDD or
was very memory intensive I'd not be too bothered about it. :-)
One way of keeping things running cool is to ensure any variables and search
results that are finished with are unset() from memory.
A lot of it will depend on exactly what you are intending though, I wrote a
concentric adjacent postcode mapping system for a customer's site which
could really nail a slower server.
