CSS326: Huge amount of pauses

Sat May 01, 2021 3:18 pm

Hello,

i'm using two CSS326 Switches with 10GTek 850nm MM Fiber-Optics.
I noticed huge amounts of RX and TX pauses between the two switches on SwOS 2.12 and SwOS 2.13.
Also many link pauses (every few seconds). The speed varies around 5-6gbit/s when copying files although both machines are capable of more than 10G.
Some time ago, when using SwOS before 2.12 i got steady rates of 10gbit/s when copying files between the two machines.
When turning off RX/TX flow control the speed doesn't get better than 5-6gbit/s.

I am also using a Mikrotik 10G RJ45 module for connecting one of the clients which causes no pauses at all.
Is it because of the 10GTek fiber optics? Would S+85DLC03D be better?

Greetings
