isaacs 8476aefc8e fs: Change default WriteStream config, increase perf 
This increases fs.WriteStream throughput dramatically by removing the
"higher default water marks" for fs.WriteStream.

Also includes a benchmark.  Current performance is significantly higher
than v0.8 for strings at all tested levels except size=1.  Buffer
performance is still lackluster.

Further improvement in the stream.Writable base class is required, but
this is a start.

Trevor Norris 22b84e6216 buffer: floating point read/write improvements 
Improvements:
* floating point operations are approx 4x's faster
* Now write quiet NaN's
* all read/write on floating point now done in C, so no more need for
  lib/buffer_ieee754.js
* float values have more accurate min/max value checks
* add additional benchmarks for buffers read/write
* created benchmark/_bench_timer.js which is a simple library that
  can be included into any benchmark and provides an intelligent tracker
  for sync and async tests
* add benchmarks for DataView set methods
* add checks and tests to make sure offset is greater than 0

Ben Noordhuis a329729537 buffer: speed up base64 encoding by 20% 
Remove a lot of branches from the inner loop. Speeds up buf.toString('base64')
by about 20%.

Before:

  $ time out/Release/node benchmark/buffer-base64-encode.js
  real    0m6.607s
  user    0m5.508s
  sys     0m1.088s

After:

  $ time out/Release/node benchmark/buffer-base64-encode.js
  real    0m5.520s
  user    0m4.520s
  sys     0m0.992s

Ben Noordhuis ba407ce410 bench: use res.end() for chunked encoding 
Use res.end() for the final chunk so we can benchmark the 'hot path' shortcut
in lib/http.js that packs the headers and the body into a single packet.

isaacs 43538f4f8f benchmark: Add http-flamegraph 
This is very similar to http.sh, but generates a flamegraph
with dtrace, pruning off the single-hit stacks so that we can
more easily see the places where relevant amounts of time are
spent.

isaacs 3149d2f7dc benchmark: Add net-pipe benchmark 
Just sends a buffer to a server, which echoes it back, and then measures
the Gbits/second.  Very similar to throughput.js, but using a single
process, so that it's possible to dtrace and get the jsstack frames for
profile comparison.

Ben Noordhuis 78ca555845 bench: optimize io.c benchmark 
Use static buffers. Most clock ticks were spent in malloc() and free() instead
of read() and write().

Fix measurements. Really fast runs would result in bogus results like:

  Wrote 1048576000 bytes in -0.731630s using 8192 byte buffers: -1366.811093mB/s

Ryan Dahl ac54272218 Gracefully handle EMFILE 
Implementing a tip from Marc Lehmann:
http://pod.tst.eu/http://cvs.schmorp.de/libev/ev.pod#The_special_problem_of_accept_ing_wh

Keep an extra FD around for every server. When you hit EMFILE, destroy that
FD, accept a connection, close it; in this way you can clear the connection
queue and let people know that you're overload.

No more timeout needed.
