yes typically boxes with very high I/O and network load need more of a
pool of memory free for immediate use than other systems.

It could be nice if the kernel could autotune this, for example by raising the free memory goal when memory shortage is detected, and lowering it gradually when not.

The sysctl could be a minimum from which this is calculated.
