A temporary 512 bytes buffer is allocated for every call to readHeader. This buffer isn't returned to the caller and it could be reused to lower the number of memory allocations. This CL improves it by using a pool and zeroing out the buffer before putting it back into the pool. benchmark old ns/op new ns/op delta BenchmarkListFiles100k 545249903 538832687 -1.18% benchmark old allocs new allocs delta BenchmarkListFiles100k 2105167 2005692 -4.73% benchmark old bytes new bytes delta BenchmarkListFiles100k 105903472 54831527 -48.22% This improvement is very important if your code has to deal with a lot of tarballs which contain a lot of files.

README
This is the source code repository for the Go programming language.
For documentation about how to install and use Go,
visit http://golang.org/ or load doc/install-source.html
in your web browser.
After installing Go, you can view a nicely formatted
doc/install-source.html by running godoc --http=:6060
and then visiting http://localhost:6060/doc/install/source.
Unless otherwise noted, the Go source files are distributed
under the BSD-style license found in the LICENSE file.

Binary Distribution Notes
If you have just untarred a binary Go distribution, you need to set
the environment variable $GOROOT to the full path of the go
directory (the one containing this README). You can omit the
variable if you unpack it into /usr/local/go, or if you rebuild
from sources by running all.bash (see doc/install.html).
You should also add the Go binary directory $GOROOT/bin
to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might
put the following in your .profile:
export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin
See doc/install.html for more details.
