Let me make this clear. The performance difference is that of
perception(overall boot speed, GUI startup etc.) i.e. mostly the startup
time/latency. I have not measured it but I wouldn't be surprised if the
throughput is roughly the same. Nonetheless lower latency allows me to
multitask better and keeps my workflow uninterrupted as much as possible. So
it is net productivity increase for *me*.
I think the symbol resolution on startup and linker related optimizations have
greater effect on 64bit machine compared to 32 bit machines.

Yes. No use. The program segfaults. Same with dosemu.
