Gary Rubin Posted April 28, 2006 Report Share Posted April 28, 2006 Hello all, For as long as I can remember, the VI profiler will show a max run time of 15.6ms (sometimes 31.2ms), even for vi's that run very fast. I've seen this with at least LV 7.1 on Win2K and WinXP. I don't recall whether it also goes back to LV 6.x In trying to get a handle on what's happening here, I've created the attached VI. I've found that I do see unexpectedly long loop times, but not the 15.6ms. Based on that, I'm thinking that the 15.6ms number is a product of whatever Profile is doing. I'm wondering, however, what exactly is causing these loop time variations. Is it simply the non-determinism of Windows? Is some of it due to Labview's memory management, etc.? If I was using Linux, would I see more consistent loop times? Thanks, Gary Download File:post-4344-1146232012.vi Quote Link to comment
