Bandwidth is reduced when sending large email traffic

Hello friends,

I have checkpoint firewall R80.10 topology like this:

MailServer--------->Firewall---------->Router internet---->outside

we send marketing-mail from Server to 100k-300k email addresses on the internet.

I measure bandwith and I see that:

- incomming bw from Server to Firewall is about 50Mbps

- But the outgoing bandwith from firewall to Router internet is reduced to only 10 Mbps.

So firewall is reducing throughput from 50Mbps to 10Mbps. But I dont know why.

Here is log . Pls anyone could explain me? Thank you!
