Hello,

I am using IO buffers in my application.
As far as I can tell, they are only used by buffered TCP and syslog for my
configuration.

Checking in Kconfig, I see the following relevant configs:

* CONFIG_IOB_NBUFFERS
* CONFIG_IOB_BUFSIZE
* CONFIG_IOB_NCHAINS
* CONFIG_IOB_THROTTLE
* CONFIG_NET_TCP_NWRBCHAINS

The question is, how to tune these settings?
How do they affect the system performance?

Is there any specific test I can run, or any strategy to follow to
fine-tune them,
or check system stability?

Thank you,
Fotis
