Hi,
Looking for some code on :
How to measure start time/ end time difference in mili or micro seconds...
Query exec time measure or simular purpose ?
Couldnt locate any syntax about that still...
Thanks

Hi.
Go here and read it all. It is an undocumented feature.

Thanks guys...nice info abuot benchmarking ! Great
Very helpfull, I could come up with some simple code...
Code: Select all
local KronoStart
on dostartkrono
put the milliseconds into KronoStart
put "Chrono is ON" into field KronoTime
end dostartkrono
local KronoEnd
on doendkrono
put the milliseconds into KronoEnd
put (KronoEnd - KronoStart)&" ms" into field KronoTime
end doendkrono

As I discussed in the article, for durations that short you'll want to get the average of many iterations.

Hi.
So you are satisfied with milliseconds only? This is a standard function in LC, like the "ticks" or the "seconds". I thought you were interested in microSeconds.
Note that if you do indeed go down to that level, Richard's comment about taking running averages is even more important, since the machine running such timing gadgetry has a timing mind of its own.

If you really want precision there is also "the long milliseconds" but you'll probably want an even larger pool of averages.
