[OmniOS-discuss] slow ssh login, maybee to many locales?

[PÁSZTOR György]

Hi,

I faced with that, the login onto my new omnios zone is slow.
I tried to debug.
Many of the symptoms seemed pretty the same as this:
http://broken.net/uncategorized/resolving-slow-ssh-login-performance-problems-on-openindiana/

Also in my case it stopped at the same point: after the kexinit sent.

However, on my omnios, the cryptadm list showed this:
pasztor at omni:~$ cryptoadm list

User-level providers:
Provider: /usr/lib/security/$ISA/pkcs11_kernel.so
Provider: /usr/lib/security/$ISA/pkcs11_softtoken.so

Kernel software providers:
        des
        aes
        arcfour
        blowfish
        ecc
        sha1
        sha2
        md4
        md5
        rsa
        swrand

Kernel hardware providers:
[---end of output----]

So, in my case it did not contained the tpm module.
I tried the opposite: enabling the tpm module, but nothing changed.
(Maybe it become even slower. I did not count the seconds)
So, I rewert it back, and run the same truss command, which revealed this:
There are tons's of file openings in the /usr/lib/locale dir at that point:

24556:  14.6296 waitid(P_PID, 24560, 0x080473F0, WEXITED|WTRAPPED) = 0

So, does somebody knows what is happening at that point,
why,
and how can I "fine-tune" it?

Kind regards,
