[PD] Timing the message processing?

[Christian Klippel]

hi larry,

a quick and simple way is to create a "time" object that gets the current
time (sec and msec) via gettimeofday().
should be a "empty" object with just one in and outlet that passes through
all that comes in. at the moment something comes in, get the time,
and at the end of the chain place the same object to get the time when the
processed data comes out. the difference of booth times is an good approximation
of the needed execution time.
its not that accurate, as it depends on system functions to get the actual time.
but it works, i use the same way in a jmax to meassure some things ....
_THIS IS NOT USABLE FOR REAL PROFILING !!_ to make it clear.
but its enough to get a good idea how much time is spent .....

greets,

chris
