Well, to be honest, with the current mainline kernel on >4Gb x86 machines,
we're not talking about slow performance on mainline kernel, we're talking
about "falls flat on it's face, in a jibbering heap" (if you actually stress the
machine with real workloads). If we apply a bunch of patches, we can get
the ostritch to just about fly (most of the time), but we're working towards good
performance too ... it's not that far off.

Of course, this means that we actually have to get these patches accepted
for them to be of much use ;-). -aa kernel works best in this area, on the
workloads I've been looking at so far ... this area is very much "under active
development" at the moment.
