thanks Hlaaftana! I take the first advice in iterator, cleaner than before, 
about toSeq it doest seems to improve. and last one ,it's not familar to me in 
javascript or python,I usually use index directly access fields, besides the 
most large table is using string key as it store chinese word.the bottleneck 
maybe somewhere else I think.
