Could someone write a quick recap of this for those of us who are 
interested and happened to miss it?

Thanks,

Morey

Everyone on the call seems to be waiting for someone else
to respond.  I'll do it just to make up for dedup :)

- Chris said he saw major performance problems from pdflush
   and he is currently working on a btrfs thread to fix this.

- Eric has been testing v0.16 single-stream-write performance
   and is seeing kswapd issues (also part of Chris's fix)
   and will take Chris's code as soon as it is ready.

- Josef is rewriting the in-memory extent allocator to make
   it perform much better and will also fix multithreading.

- Ming Ming and Chris will try to arrange a general
   breakout session for all filesystems at the plumber's
   conference in september. (Chris is presenting a talk
   on btrfs at the conference)

- I listened and contributed only this synopsis.

Thank you.  Also, did they get around to talking about when they are
going to merge in some of the queued up patches?

We have never discussed code merges on any calls.

Probably because Chris does all that merge work.

I would not expect anything until he finishes the flush thread.

Anyone comes forward with a sumary of the conf call?

Thanks!

Re: Btrfs conf call

Call summary:

Chris has been rewriting fsync to improve performance
    - 10X better multi-threaded scaling for regular files
    - directory fsync performance has not been addressed

Ric noted that Josef's fine-granularity timer work
in the main line could boost btrfs fsync performance.

Eric has seen single stream write performance drop
after v.15, his runs indicate allocator-induced stalls.

Josef is working on allocator fix round 3... round 2 had
regressions in some benchmarks.  Chris proposed he try a
design midway between the round 1 and round 2 code.

Eric noted build problems with older kernels (2.16.18 ?)
because of the btrfs NFS patch... needs volunteer to fix.

Eric and Chris discussed testing using some of the xfs
tests without using the complete harness suite.

More plumber's conference discussion, Chris's btrfs talk
will be fairly high level (as expected given where we are).
Attendance is expected to be good on all days including
the last day (so if I go, I won't leave early).  How to
set up the filesystem BOF is pending plumber's site update.

Just wondering if anyone has a re-cap of the meeting?

Would a recording of the conference call posted on the website be
unreasonable to ask for? If people want to know these sorts of things
but can't make the call perhaps it would save everyone time.
