file IO uses the disc much more than the processor (close to 0 processor usage), so there is ur answer.
in excel, the processor only comes in during calculations.
Ikr, this is the first time I heard cpu affect excel.

Well there do have company who is still using excel file to have their data stored and accessed. Even oil and gas company is using it. One of the reason they choose to do this is because it is cheaper compared to business solution like CMS. Most complete CMS in the market cost quite some money, which they find it not necessary. Even some of MIMOS data is using excel to do it, including semantic web data. My friend intern at there, his first job is to do data cleaning, damn sad

Of course they did it in a good way, with normalization and splitting of data into different file and not dumping everything in one file

So the noob 5400rpm does kacau la... my core 2 duo back in hometown almost hang when my mum do excel.. now it explained... her sifu in excel dunno y it like tat too
Disk speed and amount of RAM affect it. The slower your HDD, the slower you load in your data, so you see a hang or lag when you open the file. RAM also affect, when your data is so big, you just got 4gb of ram, there is not enough ram to keep hold of your data, so you will face the same things again. So next time check first before assuming the thing like extreme cpu is needed.
