Hi Peter, Hello Everybody,

Peter in one of your post you mentioned that the mutex which is used/needed for access the MyISAM Key-Cache is a scalibity limitation.

I believe you mentioned that the mutex is hold for the time needed to copy the key-cache block from/to the thread space.
Do I remember this right?

Wouldn't this mean, if we could accelerate the function which copies the key-block, then we will improve MyISAM scalibity?


Do you know by chance which MySQL function is used for copying the key-block?
I would guess "bmove512" is this correct?


If this is true then it might be real easy to improve this.
As accelerating this function is not difficult at all.


Cheers
Gunnar
