Currently, if a client of crypto/tls (e.g., net/http, http2) calls tls.Conn.Write with a 33KB buffer, that ends up writing three TLS records: 16KB, 16KB, and 1KB. Slow clients (such as 2G phones) must download the first 16KB record before they can decrypt the first byte. To improve latency, it's better to send smaller TLS records. However, sending smaller records adds overhead (more overhead bytes and more crypto calls), which slightly hurts throughput. A simple heuristic, implemented in this change, is to send small records for new connections, then boost to large records after the first 1MB has been written on the connection.

The Go Programming Language
Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.
For documentation about how to install and use Go, visit https://golang.org/ or load doc/install-source.html in your web browser.
Our canonical Git repository is located at https://go.googlesource.com/go. There is a mirror of the repository at https://github.com/golang/go.
Go is the work of hundreds of contributors. We appreciate your help!
To contribute, please read the contribution guidelines: https://golang.org/doc/contribute.html
Note that we do not accept pull requests and that we use the issue tracker for bug reports and proposals only. Please ask questions on https://forum.golangbridge.org or https://groups.google.com/forum/#!forum/golang-nuts.

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 file). 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-source.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 https://golang.org/doc/install or doc/install.html for more details.
