When I use arp poisoning and redirect the traffic I get a huge downgrade in bandwidth (200kb/s->20kb/s), do you think it's because of the packets loss % or something else can cause that ?

Potentially, but I think a network capture on both victims would surely explain it. At some point you might be even getting some asymmetric traffic: packets from A to B go through you, but from B to A don't, until the ARP cache is poisoned again.
I'm not a coder (or a shitty one :)), so I can't infer from your code things like how often do you renew your poisoning.
Unfortunately I can't really capture the network on both victims, for lack of devices one of the targeted machines is my router :/, I guess I should just borrow one.
Good idea on the arp cache, I even had a problem with the refreshing rate at some point so I increased the rate but maybe it still there but not noticeable. Thank you :)
