Re: memory mapping or not?

 

Hi Michael,

Do you have any details on the issues? Did the remap just fail?

As far as I can tell, a remap results in all memory blocks being used for the file becoming invalid.

If this is the case, then the operation is way too expensive with the file grows over 1GB.

Hi Paul,

I actually had some issues with the remapping in cases where the files grow larger than the main memory of the servers (don't ask).

But I can see the advantage of using mmap.

Michael
