Re: Unable to utilize past 1 gbps

Dear Marius,

In addition to that attached please find a screenshot from Proxmox on
statistics.

Do you know any ice cast servers that puts out more than 1 gbps for a
longer period? Just curious whether anyone was able to go beyond 1 gbps for
an extensive time.

Thank you!

Best,

Zsolt
