How do they connect to the internet? If dial-up, one might have better modem speed. Yes, celerons are slower than their counterparts...largely because of less internal cache. Total system memory and the video system are factors. You might be able to improve performance by some basic cleanups of spyware/adware and cache. A good defrag might help if it's been a while.
I have a Dell Inspiron 1100 that seems to operate very slow when it comes to using the Internet(really noticeable when playing online type games).I have another older Dell laptop(Latitude)with a Pentium-2 processor that runs circles around it.The Inspiron has a Celeron processor,2.0ghz,Win-XP,30 gig hard drive(20 gig still available)384mb ram.Is it normal for a celeron unit to operate slow??.If anyone has any suggestions or tips on how I can speed it up or if there is a problem,fix it if possible,please let me know.
