OT: Speeding up a slow computer

Just about every desktop computer in the past several years has had the bottleneck at I/O instead of processing power.

2) Split your discs. If you have four partitions on one disc, you still have the latency of one disc.

Wouldn't it make more sense to move the swap rather than C: ?I guess it depends how much memory he has and how often the swap is used. Does Windows allow you to put your swap drive onto a USB flash drive? They tend to be pretty quick if you have a spare USB2 slot, and you can get a gig or two for pocket change these days. Then you could have Windows on one hard drive, games, programs and data on another and swap on USB, for super-fast performance=-)

But do max out your memory first, as Will suggests.

Flash memory has slower data transfer rates when writing than hard disks (see this Ars Technica benchmark page) though reading is faster - the biggest advantage it offers is lower seek times.

A bigger downside of flash memory is the limit on the number of times it can be written to (typically in the tens or hundreds of thousands per block). Having data that is written to very frequently (which a swap file will be) may shorten a flash stick's lifespan to mere months.

IIRC, it isn't normally possible to move the pagefile (swap) from C:. I'm sure there's some hack to get it stored elsewhere, but it's likely one of those annoying things that resets itself all the time, so more trouble than it's worth. As for using a thumbdrive as swap space, like AstralWanderer said, write times are slower. Although the overwriting of data isn't really that big of a deal unless you are doing very memory intensive tasks that start and stop new address spaces a lot (most people don't). It's easier for a virtual memory manager to keep a page in swap even after it's read back into main memory, since if the page is not dirty and is picked to go back into swap, the manager doesn't need to write it again, which increases performance a bit.

And Xrati has a good point as well. Norton et. al. tends to slow things down a lot, since they actively scan files in the background. Not computationally intensive, but very I/O intensive, and that will slow things down a lot. There's better products out there.

I had no trouble at all moving swap to a different partition when my C was running out of space in the past. Maybe windows decided not to move it back to C due to lack of space, maybe it works as advertised. Hard to say. Still, I've always found claims of actual performance gain from shuffling swaps around to be rather dubious...

Well, 2 gigs is plenty for XP, I really don't think your slowdown is due to insufficient ram (unless you have a bad mem stick in there, I suppose). I think it's just Windows rot.

If that's the case, you can defrag and clear the registry and uninstall unwated crap to get some of your performance back but you really need to wipe the hard drive and re-install the OS (or re-install some OS, anyway). It's the only way to be sure.

Indeed, the suggestions here have been quite useful, for which I thank you all. There is one more thing I'd like to ask though...I currently use Norton (I know, I know, it's the spawn of the devil), and would like to remove it and replace it with something less bloaty. However, I seem to recall hearing that it has an, umm...aversion to being removed. What would be the best and most thorough way of removing it? Also, if I'm going to remove it I'd like to have a replacement in place before I'm left anti-virus free As such, any suggestions on a quality, non-bloaty, (preferably free) alternative?

Again, thanks!

That depends on whether you want a free AV, or a paid AV. AVG is a good free option, but like all free versions, its detection rates are not quite as good as commercial AV engines. This site has results of periodic AV engine tests (on the best commercial versions of each AV engine IIRC), very useful:

Avira and NOD32 tend to come out on top, especially in the proactive tests (which test detection of viruses with old definition libraries, testing the ability to identify new viruses).

As for removing Norton AV, Symantec bowed to pressure and released a complete uninstaller tool:
