I am happy we can work together on making that page better and more
realistic.

Hmm, I don't remember having written in the doc the thread-safety was
wrong. It's a closed case anyway.

Thanks for making the update. I was relating to 0.3, but of course now
the state of the art with libssh is 0.4.

I saw the results several weeks after you wrote them. I began working
on real benchmarks before giving up. I'm sorry I waited so long before
writing this mail.
> I guess that makes me "no competent network developer".
You'd be no competent network developer if you seriously believed your
benchmark was representative of anything. By your explanation, I see
that was not your intent, but the way it was described on the page
could lead to confusion.

2.3 is precise for me. I think it's all possible to do a test in an
unbiased manner. Thanks again for having removed the litigious parts.

I was considering but other developers did not want. We do not see the
licensing as an issue.

What you say is true in a sense, but as been shown to be false for
other communities such as kde and gnome. We are at a point where we
have two codebase largely different and incompatible, having different
features, strengths, weaknesses and bugs. This makes the choice
possible for the final user, when a one-size-fits-all approach may not
be suited to the particular needs of that user.
I know you weren't at the origin of the libssh2 project. I just want to
add that the first release of libssh was made in 2003 and I never
refused any contribution.
> Thanks for all the corrections and clarifications!
I thank you for your quick intervention and cooperation. I want our two
projects to communicate and exchange in a constructive manner. Would
you want that we provide a comparison page between libssh and libssh2
on libssh.org ?
Regards,
Aris
