Does that mean this latency value is "static" (e.g. won't change during lifetime) ? Would it be possible to make it "dynamic", e.g. update the latency value based on both real latency and link saturation (or maybe better wrap the read accesses to the latency value into a CPP macro to have a centralised way to make dynamic calculations without having to change lots of places in the codebase later) ? BTW: How does the topology code handle DR ? ---- Bye, Roland -- __ . . __ (o.\ \/ /.o) [EMAIL PROTECTED] \__\/\/__/ MPEG specialist, C&&JAVA&&Sun&&Unix programmer /O /==\ O\ TEL +49 641 7950090 (;O/ \/ \O;) _______________________________________________ perf-discuss mailing list perf-discuss@opensolaris.org
