Or is 8GB of ram very cheap suddenly? Well, tmpfs is swap-backed if necessary. That's one of its strengths. =20 And no, 8 gig of at least registered memory (what my Opterons use) isn't=20 cheap -- I paid >$1000 for mine a year or so ago, but it sure is nice,=20 combined with a dual dual-core system (Opteron 290s, upgraded ~4 months=20 ago from 242s). MAKEOPTS=3D"-j20 -l12" keeps things from getting too out of hand. It'll=20 sometimes use 3 gigs or so of app memory (and about the same tmpfs it=20 appears), but not too bad. I ran -j (unlimited jobs) for awhile, and=20 it's fun to see the jobs climb to several hundred, but even with 16 gigs=20 4-way striped swap, the system goes draggy at that and >10 gigs into=20 swap. Keeping it to ~12 jobs means responsiveness stays reasonable, at=20 least with the new 2.6.24 user based scheduling and the portage user kept= =20 to the same or half the share of my regular user. Swap seldom gets used,= =20 and if it does, it's only a few megs of the apps I don't use much anyway=20 (/proc/sys/vm/swappiness set to 100 so it flushes apps, not cache, to=20 swap, as apps and the main system are on raid-6 so only two-way striped=20 while swap is 4-way striped).
