SCP issue on FreeBSD

[Venkateswara Rao Dokku]

Hi,

I am using FreeBSD 8.4 as guest on top of the linux (ubuntu 14.10) host. I
observed that, the Pushing a file from FreeBSD is giving good performance
over Puling a file from other linux box to FreeBSD.

root at test:~ # *scp ns-10.5-57.7.gz root at 10.102.38.202:/root*
root at 10.102.38.202's password:
ns-10.5-57.7.gz                                                      100%
 126MB  *63.0MB/s*   00:02
root at test:~ #* scp root at 10.102.38.202:/root/ns-10.5-57.7.gz* .
root at 10.102.38.202's password:
ns-10.5-57.7.gz                                                      100%
 126MB  *11.5MB/s*   00:11

Why there is a difference between these two?. Any tuning needs to be done
on the FreeBSD guest to get these two almost same?

To see, whether its specific to FreeBSD I did the same experiment with
Linux(Ubuntu 14.10) as guest on top of Linux(same host as above). Here the
output is almost same.

root at ubuntu:~# *scp root at 10.102.38.202:/root/ns-11.1-14.4.gz .*
root at 10.102.38.202's password:
ns-11.1-14.4.gz                                                        100%
 130MB  *64.8MB/s*   00:02
root at ubuntu:~# *scp ns-11.1-14.4.gz root at 10.102.38.202:/roo*t
root at 10.102.38.202's password:
ns-11.1-14.4.gz
100%  130MB  *64.8MB/s*   00:02


Moreover, in most cases Linux performance is better than FreeBSD. Is Ubuntu
gives good performance when compared to FreeBSD?

Any help is much appreciated.
Thanks.
