Re: [Subclipse-users] Performance ofConnections

Hy Alexander,

I'm an stupid Programmer, and there facts matters me. A few weeks ago we
changed the Code-Repository from CVS to CVS. A few Problem i had, i
think you read it. But our biggest Problem today is the speed of the
connections while working on the Repository. Working on HTTP, ist slow,
but the Authentication works, working on SVN, the Authentication cannot
be done like others.

We tested it on programmers daily works, checkout, sync, commit, update
a few times, and we see, CVS is faster then SVN. I knew, SVN has a few
Features nice to have, but if the Tools are as much slower, its n Problem.

Miha Vitorovic on this List writes it's n Problem in SVN, not on
subclipse, so i may ask what can i do to fasten up this.

Alexander, i belive you, SVN should be faster, but it isn't here. Sory

Thanks for your Answer.

\Robert

P.S. i'm not only an stupid Programmer *gg*
