Hey I was wondering if there was a app like IPAdvancedTuner for mac os 9, but for os x. I got BB Optimizer, but DSL still says I have some optimizing I can do, such as :



1.Turn on Selective Acks
2. Input line speed for RWIN recommendation
3. Upload packet less than your MTU



See my full stats here:

thanx for any help kids!

Nahh. Just type in the following (or cut and paste) into terminal:

sudo ifconfig en1 mtu 1492
sudo ifconfig en0 mtu 1492
sudo sysctl -w net.inet.tcp.delayed_ack=0
sudo sysctl -w kern.ipc.maxsockbuf=524288
sudo sysctl -w net.inet.udp.recvspace=73728
sudo sysctl -w net.inet.tcp.sendspace=65536
sudo sysctl -w net.inet.tcp.recvspace=65536

the 1492 is supposedly the optimal packet size for DSL, with 8 bytes for overhead. Acks are acknowledgements, with 0 being you don't wait for the synack from the other end because most online activity is websurfing, which is fairly predictible. Buffer sizes and send and recieve spaces should be relatively self-explanatory. All of these are reset on logout, or restart. None cause any problems that I've experience in the last 8 months or so of using them.

ok, well i'm a cable modem BTW, not dsl, not sure if that matters, and mainly i'm wanting to increase my u/l cause its really weak, 16k a sec on average. and is this basicly what BB optimizer does? or by adding this ontop of BBO will I see more speeed?

get this:

ifconfig: interface en1 does not exist


any ideas?

OK. So for cable the mtu should be 1500, or the max for most routers and switches.

en1 not being there is ok. I put it in mine because I'm on airport, so I have my en, plus airport's.
