[Twg] [Discuss] FW: OpenSFS TWG Requi... - Have we achieved the single-server MD...

[Nathan Rutman]

Right, these are different things.  But both were intended to be metadata improvements.
The pdirops results have been posted, but for actual files (e.g. with OST objects) the create/unlink rates didn't show much improvement.
I have not seen any measurements of 'ls -la' for any delivered features (although that doesn't mean they don't exist).

The question now is, do we as OpenSFS members want to continue to prioritize single-server MDS performance improvements?

	hmm? pdirops is not supposed to improve directory listing, AFAIK.

	thanks, Alex

		pdirops was delivered, but the improvement results were somewhat disappointing.  I've seen no metrics for various directory listing improvements, although they may exist.
		Should we set a target rate? E.g. "ls -al" for a dir with 100K single-stripe files?

Metadata server performance
Have we achieved the single-server MDS performance goals? Do we need to move some more solid requirements to 2012?
