Realtek 8111e capped at 10mb on 10.10

[Totti]

Hi guys,

As title says - My usual download speeds have been ~ 100mb, but for some reason i can't seem to get full power on the 10.10. Has anyone else encountered this?

I am just using RealtekRTL81xx.kext - using Clover to boot. Should I be putting anything specific in my DSDT or in Clover?

Bump, still haven't fixed this issue. Tried everything! Any suggestions or people with similar issues?

I have observed the same issue, on a GA-EP45-DS4.

It does sometimes go faster but then painfully reduces speed, I have checked and the speed is reduced only for outgoing packets.

claunia@hades $ iperf -c zeus -p 6667

With zeus being Mac OS X and hades being Linux, both on same motherboard model, same switch, 1000TX full duplex no flow control standard MTU. As you can see, hades -> zeus gets easily to 813Mbit/s

zeus claunia$ iperf -c hades -p 6667

The reverse however does never get faster than 12Mbit/sec, with a mean of 8Mbit/sec.

I've been using this equipment since 10.7 and start having problems with 10.10.
