grep RealtekRTL8111 /var/log/system.log

Apple reworked logging completely in Sierra. You need to use a different command in order to retrieve kernel logs. Please see post#1 of this thread for instructions.

Anything I should concern myself with your network drive on newer versions of OSX?

Honestly, I have no personal experience with the driver on pre-SB hardware but in theory it should work fine. The only thing I'm concerned of is the fact that some users with old hardware reported performance issues due to power management which was reworked by Apple in El Capitan and Sierra.

What does "SB" stand for?

So I guess what you're saying is that Yosemite may be ok but El Capitan and sierra are a {censored} shoot due to power management. Does that problem you speak of occur even if I never let the machine sleep?

SB = Sandy Bridge. Sleep has no influence on the driver's performance at all. The problem is, that Apple reworked PM in a way to allow the CPU to stay in a low power P-State for extended periods. This is effective with regard to power consumption but may also result in a delay when the CPU has to wakeup in order to service interrupt requests which in turn may increase packet round trip time. Unfortunately this may interact with TCP's congestion avoidance mechanism which uses packet roundtrip time and it's standard deviation to make assumptions about network congestion and throttles packet rate in case of a "congested network". In short, the variation of packet roundtrip time may cause TCP to erroneously assume a congested network and to slow down operation even though there is plenty of bandwidth available.

so that problem you speak of...you feel that is only applicable to before-SB,...possibly...or are you experiencing that problem with SB too?

 

Sounds like I may just stick with Mavericks, or perhaps I will upgrade to Yosemite just to be a bit more current, but perhaps not past there.  I'm only using this machine as a server anyway...  Why rock the boat...

Mieze,

would you be so kind to place binaries under 'release' tag at github?

 

Thanks

SB is ok, like any other hardware generation which is still officially supported by macOS because Apple's developers optimized PM so that it won't affect network performance for those architectures. The problem only affects unsupported hardware and certain notebooks which may differ from regular hardware with regard to PM.

Why? Binaries can be found here on IM in the Download section. Placing them on GitHub would require additional work to keep them in sync but if you give me a good reason to do so, I might rethink my decision.
