For those who run a RTEMS 4.12 single processor application with LIBBSD, what percentage of time does your application spend in the timer server task? My NXP LPC3250 application spends about 13% of the processor time processing the timer server. Most of that time is spent processing LIBBSD's kernel callouts. I am wondering if there is an advantage to only call the FreeBSD's callout_process() function when we know a callout needs to be processed. This would reduce the number of RTEMS timer fires (which currently fire every tick).
