The testdata/e.txt input is repeated on the longer benchmarks, but the length of that data is less than flate's window size, so the numbers are essentially measuring the performance of a trivial compression. A follow-up CL will add more data to testdata/e.txt.

For documentation about how to install and use Go,
visit http://golang.org/ or load doc/install.html in your web browser.

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.
