R81.10 Open Server. 100mbit throttling. am i the only one?

So here the other day i started noticing incredibly slow performance across a site-2-site tunnel to a customer of mine..


after digging around i found out the performance issues is because of my hardware and not the customer.


Right now we are running R81.10 on open server.

has anybody else experienced throttling in performance? all kinds of speedtest/intervlan test will make the performance stuck on a roughly 100Mbit speed.


though the underlying hardware can perform much much more.


if do a "local" performance test on a windows server 2019 my copy/move file performance is a roughlt 700-1000mbit/sec.

but as soon as i do anykind of "wan" related traffic or intervlan. the speeds drops immediately to 100Mbit's.


The virtual machines + open server is running on ISCSI. 25GBIT uplink from the SAN.

the Dell poweredge server's are connected at 10GBIT.

the san is running a Raid10 with 12. 2TB SSD's and a SSH cache of  2 * 1TB NVME.

as long as i test performance with "local" speed. (not crossing the firewall interfaces) speed is insanely fast with everything i do, but everytime traffic hits the firewall. the performance drops immediately..


am i the only one seeing it?
