Not sure this is actually a bug... if your system is swapping or low on memory, the kernel will have to swap graphics related pages as well, potentially stalling graphical applications during disk I/O.

If the only <1 GiB is used and *no* swap is used (unless 4-10 MiB of swap used is worth mentioned when >1024 MiB is 'free' [used on buffer or cache]) it is error. After upgrading to 4 GiB problem was solved but it is not a statement that to use Intel cards and use I/O you have to have 2-3 GiB free. 1. Low priority jobs should *not* *significantly* affect normal. If an application have priority 19 and lowest io and scheduler priority it should *not* cause visible delays in applications 2. With similar conditions (no I/O, no swap occupied) there is no reason system would swap. In short - system have no reason to do heavy swapping. Either it's some error in subsystem design/implementation[1] (low priority jobs probably should not free used buffers of high priority jobs) or some problems with swapping. [1] Yes - I know that it is hard subsystem and I admire those who implemented it. |
