Well, the subversion library has changed a *lot* between 1.4 and 1.5 :)

No, I meant upgrading the server. Sorry for not being clear on that.

You'd have to browse through the Subversion library code which does the
'svn ls'. And I just checked: if you upgrade to Subclipse linked against
Subversion 1.5, it will be as slow as TSVN 1.5 - the old API's are now
redirecting internally to the new API.
