<p>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?</p>

<p>Any ideas how to change it?</p>

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