i stumbled accross a command called readprofile by accident and found
that by appening the line append="profile=2" to the lilo.conf file
and using thread profile command you can get statistics on functions
that spend a certain amount of time doing a job.
i done some searching on this and can't find anything other than a
man page on readprofile.
can anyone tell me what does the line append="profile=2" actually do
apart from creating the file profile in the proc directory, what is
the 2 for in this line?
next is this an accurate way to measure heady traffic load through
say a linux router? will it highlight all functions say for example
ip_forward, dev_queue_xmit etc etc that are being opverloaded due to
huge traffic loads being passed through the router. ie will it spot
bottlenecks with good accuracy?
