Bug ID: 54393
           Summary: rFactor 2 dedicated server: Severe performance
                    degradation with additional clients joining
           Product: Wine
           Version: 8.0-rc4
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]

      Distribution: ---

I'm using the rFactor2 dedicated server to host races for our team on a Fedora
system.

Everything seems fine up to 6 drivers joining, above that everyone ping started
to rise each time a new driver entered the server and we reached 500/600 ping
with 13 driver on the server.

I could still ping google from the server with low numbers.
The ping issue seemed to be strictly related to the number of drivers.

I know I was able to host with this same system on windows races for up to
13/14 drivers without issues in the past.

Some data about the test:
Speed-test for the machine running the dedicated server:
* 50 Mbps download speed 
* 17 Mbps upload speed
* 8ms ping

Whie running the dedicated server the band usage during the test was 
* lower than 2 Mbps upload 
* lower than 2 Mbps upload

RAM used 4 Gb used out of 12 of RAM
CPU at 40% (none of threads were maxed)

I remember there being a similar issue with the game itself related to
networking, operations not sure if this may be somewhat related:
