Programs are loaded from the cache in the case of >compilers, linkers, etc. The decompression is fast but takes some time. Granted, but I'm talking about files a few megabytes in size. The only cache faster than decompression is onboard cache, of which I have only 512k. There is also the cache Windows uses when loading, but I don't believe that that's a couple of megabytes in size.
