Is it possible vzmigrate without encryption via ssh or any other encryption? ssh slows down the speed. I want fast migration inside our trusted network.

Yes, it is possible(you just to need patch the transport part yourself).

Regarding speed limits you met, i've just made experiment based on 15 minut googling and testing:

coolcold@db01:/data/mysql$ scp -o MACs=hmac-md5-96 -o Ciphers=arcfour /data/testfile.bin db03:/dev/null
testfile.bin                             100% 1516MB 116.7MB/s   00:13

cpu usage was ~80% of Intel(R) Xeon(R) CPU E5645 @ 2.40GHz
So, internal gigabit link used at full speed with a bit of extra capacity.

Auto applying settings for connection:

coolcold@db01:~$ cat /home/coolcold/.ssh/config ;echo "----- || -----"
#MACs=hmac-md5-96 -o Ciphers=arcfour
Host=db03
ForwardAgent=yes
MACs=hmac-md5-96
Ciphers=arcfour
Hostname=db03
#Compression=no
