It's a while 'til 3.4. A bitfield-type enum may show up in the docs, if no
where else. ;)

Why does your benchmark create such large files? It doesn't make sense.

large to be more real world. I've just tested it, and in practice
file system doesn't make much difference, so I've fixed that now:
Thanks. I had bumped the number of files, thinking it would make things
more interesting, and it filled my disk.

I wonder how sshfs compared to nfs.
(I've modified your benchmark to also test the case where data isn't
in the page cache).
Local ext3:
cached:
os.walk took 0.096s, scandir.walk took 0.030s -- 3.2x as fast
uncached:
os.walk took 0.320s, scandir.walk took 0.130s -- 2.5x as fast
NFSv3, 1Gb/s
Very interesting. Although os.walk may not be widely used in cluster
applications, anything that lowers the number of calls to stat() in an
spplication is worthwhile for parallel filesystems as stat() is handled by
the only non-parallel node, the MDS.
Small test on another NFS drive:

Hi guys! This is my first post on this list.
I'd like have your opinion on how to safely implement WSGI on a production
server.
My benchmarks show no performance differences between our PHP and Python
environments. I'm using mod_wsgi v3.4 with Apache 2.4.
Is that ok or can it get faster?
