How can I increase performance on really high-speed, high traffic links?
If you are seeing performance limitations when using a high-speed WAN connection transferring lots of data, you may see a performance gain by altering the following sysctls: net.inet.tcp.recvspace net.inet.tcp.sendspace Try a value like 65536 instead of the default of 16384. Note that very few will see any benefit from this. Don’t adjust this unless you are actually seeing performance below what you expect.
