2.4.10-pre12 is impressive compared to pre10.
128M, 300MHz and a 3G ide-drive is usually enough for office work and compiling, but there are times I use some swap. Reading the impressive reviews for pre11, I decided to put it through a worst-case test. Well, worst-case for my kind of use anyway.
I started staroffice with 40 documents. This is slow and tends to ruin interactive performance for a long time. I used to get lots of swapping, and plenty of swapping in long after finishing staroffice.
This time I also started a kernel compile, a updatedb run, and a rgrep in /usr/src while waiting for staroffice to load. I also had netscape up. It came up, with only 10M total in swap. 20-30M just for starting staroffice used to be the case. And interactive performance was fine, even with all that going on.
The normal under such circumstances is several seconds just to raise a xterm, with typing oocationally lagging and delays when pressing enter. But only commands needing disk-io got delayed and only slightly. Typing and window moving were just like a normal X session with nothing else going on.
The rgrep seemed to proceed at great speed, the compile ran very slowly. I guess it lost the bandwidth competition.
Then I went away for lunch, and when I came back there were no more than 20M in swap. Everything had finished except the compile - it was still hampered by netscape doing one of its 100% cpu bugs.
Staroffice and netscape _still_ performed fine, all that io didn't destroy their working sets! I quit staroffice, the compile finished, and swap usage dropped do 15M.
The machine have recovered perfectly - there seems to be none of that long-term sluggishness that used to happen after updatedb or after swapping 20M. The machine used to recover to a usable state before too, but never this good. Before, I had to reboot or use it a few hours.
Good work! There's noticeable improvement for desktop use!
