Latency, error finishing read, and IRQ affinity

Thanks!

I just moved an updated rt_setup.sh script to the first post in this thread.  It detects if irqbalance is running or not and sets things up properly either way.  BTW, dual-core cpus are not completely obsolete - I have fairly recent Shuttle mini-pc's with dual-core processors that definitely benefit from having the IRQ affinities set up properly.

What is supposed to end up in NIC?  (I've got two interfaces - not fluent in awk ).. Is the 10.10.10.1 supposed to be the MESA card address?NIC=`awk 'BEGIN{nic=""} {if ($1=="iface") {tmpnic = $2} if ($1=="address") {if ($2 == 10.10.10.1) {nic = tmpnic}}} END{print(nic)}' /etc/network/interfaces`

 

The IP address in the script should match the real IP address of the host device connected to the Mesa card

Hi, awsome script! Definitely fixes latency issues.
However, I am trying to utilize this with EtherCAT master and I am getting error

I would guess it has to do something with NIC IP address not being 10.10.10.1

Nope, some new Linux Distros do not use rc.local, so do a search for the distro you are suing and how to add it, then run the script again.
Edit,
Left hand seems faster that right one, USING, should be using, not suing above!

i am stuck on the irqblance part in the instructions of that link. i created the files but i am not certain what to do from there. when i run: sudo ./rt_setup.sh, command not found. i created both files and make them exicutable and restarted and when i run: sudo ./rt_setup.sh. what to do after that. i am missing something something.

i think i have it. maybe if i took the time to read the entire thread, i might find the information i am looking for. thanks

i guess i dont have this figured out. i keep getting command not found when i run sudo ./rt_setup.sh. i know i have to do something to the file but i can't figure out what to do to make it not give me the error on exit error. please help me out
