   Hello everyone,
We are looking for a high-performance SSH solution for HP-UX platform.
The idea is to protect an existing application, so the server should
perform port forwarding only.

 A couple of requirements:
1) Should run on HP-UX B.11.11 U 9000/800
2) Hardware configuration - 1 HP server with 8CPUs 16GB RAM
3) We need to support up to 1000 concurrent connections (open tunnels).
4) The upper limit expected connection growth - 50 / minute (let's say,
1 new connection per second).

  OK, now the questions:
1) Do you think it is applicable? Can such hardware handle such
CPU-intensive requirements?
2) If so, will it work with OpenSSH or a commercial solution will be
required (maybe Tectia - please recommend)?

3) In case of OpenSSH:
 a. Do you recommend compiling for 64 bit, or just use 32bit?
 b. Is sshd optimized to run on several CPUs?
 c. Is there any way to tune number of processes / threads etc, in
order to optimize the performance?

Thanks a lot in advance,
   Vadim
