- Default ``send_bytes`` value is now 18000 instead of 9000. The larger
default value prevents asyncore from needing to execute select so many
times to serve large files, speeding up file serving by about 15%-20% or
so. This is probably only an optimization for LAN communications, and
could slow things down across a WAN (due to higher TCP overhead), but we're
likely to be behind a reverse proxy on a LAN anyway if in production.
- Added an (undocumented) profiling feature to the ``serve()`` command.
