Timings (as for change 1122043) go from 49ms to 48ms ish. It's
mostly lost in the noise, but it probably doesn't hurt.

exp/draw fast path for glyph images. · d7a6d228

Nigel Tao authored May 10, 2010

To draw.Draw a 32x32 image.Alpha 10000 times,
Before: 633ms with 10000 mallocs
After: 49ms with 0 mallocs

These times are just blitting an image.Alpha, and do not include
rasterizing a glyph's vector contours to an image.Alpha.

The "generic" test case in draw_test.go tests this fast path.

big: cleanups and performance tuning · 52cc0581

Robert Griesemer authored May 08, 2010

- removed last argument (n) from all core arithmetic routines;
  instead, use the length of the result

- simplified nat.make implementation and chose a better capacity
  for new values, removed a TODO in the process

Changing the constant e from 1 (old) to 4 (new) improved
pidigits -s -n 10000 by ~9% (on a 3.06GHz Intel Core 2 Duo):

user	0m3.882s (old)

big: implemented overlap-tolerant shifts in assembly · 3f287b50

Robert Griesemer authored May 07, 2010

- no need to make copies in cases of aliases
- removed deprecated internal shift functions
- minor unrelated simplifications

This change improves pidigits -s -n10000 by almost 20%:

user 0m6.156s (old)
user 0m4.999s (new)

(pidigits -s -n20000 goes from ~25s to ~19s)

gob: add support for maps. · 7861da73

Rob Pike authored May 05, 2010

Because maps are mostly a hidden type, they must be
implemented using reflection values and will not be as
efficient as arrays and slices.
