With 2.3.99 it uses a lot of swap. The system has anyway around 60 MB RAM unused, i.e. It don't have to use swap. I have tested also the other patchs from Rik, here they improving responsiveness a lot, the mouse moves smoothly. With them the system has a lot of memory in swap, but not a lot of swap traffic, i.e, it swaps the applications that I am not using in that moment. I have tried to mix the two, yours and him, and no way, the system begins working OK, but in some moments, the system begins to trash (very heavily). Indeed I boot the machine with mem=64MB (normally with 256MB), the same precesses for testing and the machine dies in the middle of the trashing (no keyboard, no mouse, no response) and the disk sound very loud. Hope this helps, if you want more information, me to make some tests or something, let me know.
