TortoiseSVN & Putty very slow

By : Chris

does anyone have a clue why the TortoiseSVN windows client (in Win32 XP and Vista) is so incredible slow when used with Putty and PAM? It seems it connects for each request since datatransfers (checkout) are not slow at all?

Any ideas how to change it?

Update: I had no problems with SSH before. But I have to use key based authentification.

Try using Cygwin's version of ssh.exe.

I found this advice here, and it sped up my downloads by 3-5x

Ensure that there is a matching PuTTY session.

If your URL is


then you need a session in PuTTY named


which must be fully configured, especially in means of

  • username
  • private key file

I am using this together with Pageant.

What type of system are you connecting to? If you connect to OpenSUSE, for example, default DNS Reverse Lookup settings generally cause SSH connections to be very slow. If you can, put your client side IP address into the /etc/hosts table on the server. If Reverse DNS is your issue, this will resolve (remember to restart nscd daemon - "/etc/init.d/nscd restart" so that the change will take effect.)

SSH will be slower than native SVN protocol but not by an order or magnitude and not likely to a level that you will notice. But Reverse DNS timeouts could be several seconds per request.
