Re: [gentoo-user] Dual or Quad CPU complications?
I believe NUMA is only used on multiprocessor machine and not on only multicore. http://en.wikipedia.org/wiki/Non-Uniform_Memory_Access 2012/12/13 J.

Re: [gentoo-user] SSD configuration
I think u misunderstand, i belive that what Schuster have is tmpfs always mounted on /var/tmp/portage, and PORTAGE_TMPDIR will be that. When he need more than 8Gb in some package PORTAGE_TMPDIR will be /var/portage/tmp and that on HDD. What i have is /var/tmp/portage on tmpfs config in fstab with noauto, so when i want to emerge a lot of things i mount that. 2012/11/26 Jacques Montier > 2012/11/26 Alex Schuster > >> Luis Gustavo Vilela de Oliveira writes: >> >> Well, with 8Gb RAM, i recommend use tmpfs on PORTAGE_TMPDIR, just while >>> u are compiling anything. >>> Or even with 6Gb too. >>> >> >> I have 16 GB, with 8GB for $PORTAGE_TMPDIR on tmpfs.

Re: [gentoo-user] SSD configuration
Nice way to handle that. I only had problems with libreoffice. But i mount the tmpdir ondemand, and when libreoffice needs update i use the SSD instead. I have 16GB too, and in general use 4GB for tmpfs on TMPDIR, i think only some packages need more then that. 2012/11/26 Alex Schuster > Luis Gustavo Vilela de Oliveira writes: > > Well, with 8Gb RAM, i recommend use tmpfs on PORTAGE_TMPDIR, just while >> u are compiling anything. >> Or even with 6Gb too. >> > > I have 16 GB, with 8GB for $PORTAGE_TMPDIR on tmpfs.

Re: [gentoo-user] SSD configuration
Well, with 8Gb RAM, i recommend use tmpfs on PORTAGE_TMPDIR, just while u are compiling anything. Or even with 6Gb too. I don't worry to much about use the SSD, the only thing that i do is use distfiles, music/video/photos on HDD to safe space. And the TMPDIR thing when i'm compiling a lot of things. 2012/11/26 Jacques Montier > > > 2012/11/26 Daniel Troeder > >> On 25.11.2012 22:43, Jacques Montier wrote: >> > Each time you sync the portage, you should write on the SSD... >> > Is it a good thing ? >> It is the best thing since rsync!

You should look at the BIOS config, if AHCI is enable. 2012/11/25 Jacques Montier > Hi all, > > I bought a 250Go SSD M4 Crucial , read (of course) Gentoo documentation > and installed the drive on my desktop pc (Asus MB, Intel ie7 and 6Go RAM). > > 1- Everything seems to work perfectly, but i would like to know if my > configuration is ok or could be optimized. > > /tmp and /var/log are on tmpfs > /boot, / and /var are on SSD (sda), > swap, /home, /usr/portage, /var/tmp and /var/log on a 1To SATA HDD (sdb) > You can see my attached file fstab.txt > > 2- When booting, BIOS seems to detect the SSD as IDE not SATA ; anything > wrong ? > > Thank you very much for your response, > > Cheers, > > -- > Jacques > > > > > >

Just try, and chromium get crazy too. I'm using chromium 24.0.1312.5 with KDE by the way. 2012/11/11 Grant > Does anyone else's chromium get a little crazy when they try to bring up > the print dialog without a printer attached? > > - Grant >
