I think you meant /usr/portage/distfiles, right? Yes, you can remove them. They are the source archives of the packages you've installed.

Often the bigger problem with large binaries is that their working sets exceeds the sizes of the L1 and (possibly) L2 caches. So, you may well be right that your gigabytes of RAM greatly reduce disk access to load and demand page applications, you may still get a slowdown due to cache misses. Central memory, which is the fast small storage when considering demand paging, is the large but slow storage when considering caching. allan -- gentoo-user@gentoo.org mailing list

It depends entirely on the application and processor. Compared to -O2, somethings are faster with -Os and some things are slower. Same with -O3. It can even depend upon the options given to an app, for example bzip2 -9 will be faster with one level of optimization than with another, while bzip2 -1 can give the complete opposite results. I chose -Os for my system, but only after testing the things that I care most about (compression, dm-crypt encryption, some media encoding) to see what was best overall. But even that was a comprimise, and the real deciding factor was that it took a lot less time to compile with -Os compared to -O3. -Richard -- gentoo-user@gentoo.org mailing list
