Git Clone is too slow

Question

This is my first time to construct the git server. When I use TortoiseGit-1.8.1.0-32bit to handle the operation, everything is fine!

But if i use the git clone

Answer 1

Maybe you can fetch only the latest revision first and then fetch the rest:

$ git clone --depth=1 git@github.com:joe/hello-world.git
$ cd hello-world
$ git fetch --unshallow

Thanks this article!

Answer 2

There are two issues at play here:

1. Your OpenSSL is not up to date
2. The SSH protocol is slower than HTTPS (but not by much)

Part 1. OpenSSL

After following the directions from the article, http://darrell.mozingo.net/2011/09/29/painfully-slow-clone-speeds-with-msysgit-gitextensions/, I successfully boosted my network throughput for the git clone operation from 1 MiB/s to 28 MiB/s. This result was achieved by upgrading OpenSSL from version 0.9.8e to version 1.0.1e.

Part 2. SSH protocol

The SSH protocol a little bit slower than the HTTPS protocol, but not enough to warrant the speed differences I mentioned in Part 1 or what you are seeing. Please read through this article for more information on the Git protocols: http://media.pragprog.com/titles/tsgit/chap-008-extract.html.

Answer 3

If you, like me, have configured TortoiseGit to use Putty's plink to connect (and use pageant, etc...), this might help you:

Try enabling in Putty (Default Settings) the following settings:

1. SSH -> Auth: "Allow agent forwarding" (I believe this is the one that changes "everything")
2. SSH -> "Enable Compression"
3. Session -> Select "Default Settings" -> Save

For me, this resulted in going from 143.00 KiB/s to 4.50 MiB/s

Hope this helps.
