tinc - May 2004 - Performance problems on solaris x86

Hi!

I've successfully installed tinc on Solaris 8 x86. Everything seem to 
work ok except for one thing, I get 5kb/s transfer rates over a 100mbit 
TP connection. Is this a known problem or have I made some mistakes?

My setup is really simple:

anna(Win XP - Tinc 1.0.2 using the Win32-TAP driver) <=> LAN <=>
sara
(Solaris 8 x86 - Tinc 1.0.2 using the TUN/TAP 1.1 driver, OpenSSL 
0.9.7d)

Another funny thing is that tincd core dumps when I use the
"-d<N>"
argument on the Solaris machine.

My setup:
root@sara# ifconfig -a
lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000

How exactly are you measuring the transfer rate? Since one end is Win
XP, try raising the priority of the tincd process in the task manager,
it seems to help.

Hm. Could you send the config.h and config.log files that were created
when you compiled tinc? If possible, could you use gdb on the core and
show us the result of the backtrace command?

I would blame the slowness on the windows side.  tinc on windows has been
known to be slow.  I've seen some improvements running the latest
development win32-tap driver (as opposed to the one that ships with the tinc
windows package) but its still nowhere near the speed and (low) latency of
tinc running on *nix.
