Hello,
The new kernel 2.4.21-pre4aa3 is running now, but the box behaves similarly. It still swaps quite a lot and much more than the rmap vm. Both servers are under the same load.
One difference is the amount of free memory:
r b w swpd free buff cache si so bi bo in cs us sy id aa: 0 7 0 5773620 202416 118076 2069716 5330 746 5330 766 4845 5597 12 14 74 rmap: 0 0 0 3498044 13572 4144 4754596 74 0 75 6 642 598 5 3 92
The aa kernel keeps ~200MB out of 6GB of memory unused. I'm not sure, but if we could reduce it perhaps there would be much less swapping. Is there a way to achieve this?
Another notable difference between the two vm versions is that the rmap vm maintains about 80% of memory on the active list and the aa vm much less: between 4% and 12%. The rmap vm must use more CPU, but these servers have a lot of processing power so it is not noticeable.
Cheers,
