The default configuration tries reduce the latency for a typical desktop system and protects the system from malicious processes/groups. With a different configuration all other types of systems can be adjusted as well. Website: =95 Ubuntu PPA: = =95 Latest Release: What's new in 0.3 (very short version)? =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D =95 X-Server plugin which monitors the active windows and gives more priority to the recently active windows. =95 Full scripted scheduler with flexible configuration that allows easy adjustment of the resulting cgroups and parameters. =95 Protection rules against common cases of memory shortage, also known as the swap of death (even without swap). =95 Scheduler configuration for desktop systems =95 Fast C core with Lua embedding. Intelligent caching to reduce the load on filter rules and scheduler. =95 Very detailed API for system inspection and adjustment. =95 Rudimentary Rules for popular Desktop Environments KDE & Gnome Does it work ? =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D Yes. Of course it is possible to still cause a swap of death or overload the system so much, that it starts to get lag. But typical cases get caught by the current rules. A make -j 50 of the linux kernel on my dual core machine with 4 GB ram let me still work on the machine quite well, but a make -j 80 still locks it down for like 4 minutes. This is most likely because the heavy swapping done on the isolation groups (their main memory usage is restraint). This may be fixed by using the blockio subsystem, but this is not used yet. Planned for the next version. kind regards Daniel Poelzleithner --------------enigE2743C3C8693CDC6D1649C32 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQIcBAEBAgAGBQJNNXIKAAoJEFYpgV2Roepc2pEP/35aeJw/isjU3v2kYBRcxGEj FDqw4vJ3WIfSnv/Gnrv0PS/56DOwSlNH1KHtIgjGi8ICWzwQSbk8NuSHQUEd5vXr XBjQchkLmTHSfK0dC9c1X3NpJzhC23AFHcPhcfNqEk8QX7gUyk8ac8wFqa9TG3eS w7szX90vzYV/vpCOzGniMTvn01Q1MpZx+SOYgmQYxWVcqRBjqAA+am6i/w7VSy7a /Kncej+TKS1Xclv9VXXHFDbtaORx8nXpXGrhq6UTfL1fh0y9ibYO6cCm9ysShxTT q+thZguYAPe8HWEEVEs/kChSkpn+zCAcEL252ySOFSVtAPjQlATqBywJBvIm4Krf xP/FtOwOwVcHmR5wpVPsLLEzlTAHLfwP7gT8R6ERaQef4UoDyBbgwBjCCMZ6nu4L +bCeEeAc+qes+6ehEbkD6N2gtzv7zld5QEo5a1uv9FHxLu4OVv6z6+wjK2KdVci5 Ar527vxzH7Q3IclfelzkGDt5Ojgn/20x6yHFLxNfXWvQas+z/w6FTlQFCdgiKnae 3P6ZRbeQuh3VSVt3okrlmx7EcN++FX3R4DDnKONGFL+oPbo/f3K4v4OGj44TZxXh CEbsVYZbA+5ELlh7fAE3GOKgWTX1WB0KQ2rqou8/7X+X/mYF+CkQybme0MCzICoe zcnsIhMr/NXG6eK7ITgL =bosV -----END PGP SIGNATURE----- --------------enigE2743C3C8693CDC6D1649C32--
