It depends on what your limiting factor is (any combination):
  • Time
  • Memory
  • Network bandwidth
  • Processing power
If time is not a limiting factor, then it doesn't matter which method you pick :)
If Memory is not a limiting factor, move your database to a ramdisk.
If Network bandwidth is not a limiting factor (but at least one of the others is), you'd have to benchmark both options.
If Processing power is not a limiting factor, you could just let mysql do it's thing (least effort).

Also something that might often do you have to perform a query like this? If the answer is more than 'occasionally', consider letting mysql index the column.

[pryrt]: In the link brackets...
[stevieb]: guys, not *your* mother, "Your Mother" here on PM. Sheesh. Like I haven't spoken to your mom
[stevieb]: pryrt the brackets work in such a thing? I have nobody to test against. I will try :)
