Latency Patch for Mac

[PallyPower]

I was wondering if any of you paragon raiders or anyone out there uses a Macintosh computer while raiding, and what latency patch(es) you use. All of the patches that I have been able to find, such as leatrix, are all for windows. any help would be appreciated.

You don't need a "latency patch" for Mac OS X, since it already works as it should (unlike Windows).

yea I was just wondering if there was anything I could do on macs to lower latency. Didn't realize that the patches were only for windows. however bought new internet down to 50 latency so im happy :D. thanks!

Leatrix Latency Fix disables Delayed ACK on Windows. The same mechanism is ON by default in Mac OS X. To disable it you can run:

Code: Select all

sudo sysctl -w net.inet.tcp.delayed_ack=0

It's not actually explicitly "on", it's in "auto" mode which seems to work reasonably well for the case of WoW - I see exactly the same latency on unmodified OSX 10.5 as I see on "patched" Windows when playing from the same network.

Code: Select all

delayed_ack=0 responds after every packet (OFF)
delayed_ack=1 always employs delayed ack, 6 packets can get 1 ack
delayed_ack=2 immediate ack after 2nd packet, 2 packets per ack  (Compatibility Mode)
delayed_ack=3 should auto detect when to employ delayed ack, 4 packets per ack.  (DEFAULT)


PS. Yes, I know 10.6 is out, but I employ the strategy of "don't fix something that's not broken" on this laptop...
