2 gig for the CPU is not much info, it's just the speed of the CPU, there are many different CPUs of varying speeds that run at 2 gig. Would be like saying "my car engine is a 2 liter, is it fast?".
A Pentium 4 2 gig is pretty slow. A Core 2 Duo 2 gig not as much, a Celeron at 2 gig would be slower than a non Celeron Intel chip at 2 gig, AMD at 2 gig may be slower or faster than an Intel chip depending on the CPU model.
You should list full system specs, CPU model, RAM type, Motherboard, hard drive, etc... You may be using an old laptop for this with a 4200 rpm hard drive which is a lot slower than a desktop with a 7200 rpm hard drive.
