----------------------------------------
I don't mean my repair is not efficient , for some server of low pofile, doing
repair may got affect .And the issue are all not resolved. For changing hash is
a way to alleviate this problem,but I think it may be dangerous ,sha-256 will
got very low probability of data collision.
> Throttle the speed of merkletree row hash

> Under our enviroment , we may got some Low-profile servers, like 4core 8G
> memory, so when doing repair for merkletree calculate , the cpu may cost so
> much. And we think repair can take long time so do some speed throttle may
> increase repair timeļ¼but can make the server more stable.
