As with any application, the quantity of RAM, speed of the processor and bus, and available hard drive space and speed of the hard drive are all determining factors in the performance. If your computer is totally reliant on the hard drive for use as virtual memory, overall performance will be slow. If there are a lot of temporary internet pages cached, performance will decrease. If there are a lot of applications set to start up automatically, this will slow down the computer boot an use available RAM.
