I have one trivial idea : would it help to use 2 addresses to server data, one for pure kernel usage (eg: git, rsync) and one with other stuff such as DVDs, but with a low limit on the number of concurrent connections ? > The most fundamental problem seems to be that I can't tell currnt Linux > kernels that the dcache/icache is precious, and that it's way too eager > to dump dcache and icache in favour of data blocks.

Everything is consumed in dcache/icache and no data blocks are cacheable anymore. I never found a way to tell the kernel to assign a higher prio to data than to [di]cache. To remedy this, I wrote this stupid program that I run when I need to free memory. It does simply allocate the memory size I ask, which causes a flush of the [di]caches, and when it exits, this memory is usable again for data blocks. I'm not sure it would be easy to automatically run such a thing, but maybe it could sometimes help when the [id]caches are too fat.
