List,

File transfer between my iBook G4 and OpenBSD box (3.8 GENERIC#138 i386) over SSH seems really slow. I have made sure the iBook en0 interface is 100baseTX full-duplex and the same with the rl0 interface on the OpenBSD box. When transferring files with scp or rsync (over ssh) top reports sshd at 80-85% and transfer speed is limited to anywhere between 70-80k/sec.
The OpenBSD box specs are as follows:

cpu0: VIA Samuel 2 ("CentaurHauls" 686-class) 533 MHz
cpu0: FPU,DE,TSC,MSR,MTRR,PGE,MMX
real mem  = 158900224 (155176K)
avail mem = 138125312 (134888K)
using 1965 buffers containing 8048640 bytes (7860K) of memory
rl0 at pci0 dev 20 function 0 "Realtek 8139" rev 0x10: irq 11 address x0:x0:xc:x9:x0:xf

so it isn't the fastest box in the world but I'd expect it to cope better than it is. I have tried FTP and speed is constantly around 500k/sec, which I can live with but realise it should be much faster. FIrst thoughts is possible bottleneck when waiting for more entropy. If this is the case would adding memory make a huge difference?
or is the CPU the bottleneck?

any ideas out there?
i'll continue googling in the meantime....

thanks guys,
