Apologies for corrupting the thread by creating a new message, but I seem to have finally been bit by the "missing emails" issue, so I don't have a message to reply to. I found this in the archives: >> You mentioned problems compiling.

Maybe not. With -O3 FEX, some programs can take 200-400MB *per module* to compile. It all depends on the complexity of the code, and the problem would be particularly acute with C++ programs (which I know blender is not C++, so this is just something to keep in mind). >> Indeed when compiling most programs, you should see very little >> if any disk activity. > My SATA disk (Seagate ST3200827AS) is heavily shakeing its head when > compiling... Run top in another window while this is going on, and keep an eye on your swap usage. If you see any swap being used at all, that is a bad thing. >> This is particularly suspect if you have >> something like MAKEOPTS=-j4. > Yes, normally I use "make -j 4" for useing both cores. Try with -j2. -j3 is ideal for keeping a dual-core CPU busy, but will still take a huge amount of RAM, so unless you add another GB of RAM, I recommend no more than -j2. And if you are about to compile a big C++ package (like KDE or OOo), drop to -j1. -Richard -- gentoo-user@gentoo.org mailing list
