Performance guide question

[vicking]

Hi all,

For my system I followed this guide;

https://docs.opnsense.org/troubleshooting/performance.html

But there is one thing of which I am not sure what value to use.

net.inet.rss.bits = X
This one is dependent on the amount of cores you have. By default the amount of bits here represent the amount of cores x 2 in binary. This is done on purpose to provide load-balancing, though there is no current implementation for this so we recommend setting this value to the amount of bits representing the number of CPU cores. This means we use the following values:

for 4-core systems, use ‘2’
for 8-core systems, use ‘3’
for 16-core systems, use ‘4’
Etc.

I have a 6 core Intel 9500T and don’t know if I should use 2 or 3 now.

Any ideas? Thanks!

Use 2. Four cores is plenty enough.

What to set for a 2 core system?

What to set for a 2 core system?

1, obviously :-) (2^1=2)

And if you are lazy like me..

Use the bit position...
