EoIP 450G low speed

I have about 2% pocket loss to remote gateway thrue EoiP (Internet have 0% loss between each other)
In one tread TCP speed about 5 Mbit
If run many torrents about 200 connection i can get 80 Mbit with cpu load about 25-30% 450G board (100M link)
Other side is x86 system and it’s has no trouble to him 10% load 1G link

Still actual is any advices ?

Can you describe the path between the two systems and check the latency between them?

Main side X86 system 1G internet link white IPv4
Remote side 450G 100 mbit link white IPv4

latency 1-2 ms pocket loss 0%

Thrue EoIP tunnel pocket loss 2-3% speed described above.

Both networks use same internal ip subnet.
I need connect Remote side to main side with all services that running at main side include internet connection ..

CPU load main side 10-20%
CPU load at MT450G 20-40% …

Still actual …
If anybody need extra info plz post what exactly.
