Some profiling data:

mid_eval:          24%
is_attacked:       12%  (is called in eval for kingsafety)
movegen:           11%
SEE:               10%
search:             6%

Without eval:

SEE:               14%
movegen:           14%
search:            13% (most expensive: picking the highest ordered move)
move ordering:      6%

Without eval+SEE:

movegen:           27%
search:            11%
quiesc hash probes: 9%
move ordering:      8%
