| |
This patch seems to be (very) optimized for systems with low memory (<32 Mb). In my P100 with 32Mb it takes too much CPU time (almost 40%!!), but if I take 16Mb out of the motherboard the system seems to be faster with the vhand patch than without it.
Other thing about it is that it almost disable swapping, except when you are really low on memory, for example, without it the getty process and other process were swapped out, but with the vhand patch, they stay in memory (I mean real memory) until there is no space to allocate new process, lowing the cache and buffers to less than 2Mb. This doesn't seem to improve system performance (in the contrary compiling the kernel takes 20% more time to finish).
In conclusion, the idea seems good, but you have to polish some things. I think, that it would be a good option in the config, or even it can be automatically enabled if you have less than 32Mb, but for now I prefer just 2.1.65 (by the way, well done guys!)
