Description Nicolas Brisset 2006-12-20 17:56:53 UTC

Version:           1.3.1 (using KDE 3.4.0, compiled sources)
Compiler:          gcc version 3.4.3
OS:                SunOS (sun4u) release 5.8

I had not used this in quite some time, but I wanted to show someone how you can "scroll" through data by loading it on demand with the "advance 1 screen" action, and it is awfully slow. I have tried it with various datasources, and all are very slow.
It is in fact so slow that there must be a bug somewhere. Advancing 200 samples at a time with only one curve from gyrodata.dat takes 4 seconds each step !! (Loading the complete vector is faster !)

Hmm, I can't reproduce this. I'm running "kst -y 1 -n 200 -f 0 gyrodata.dat" and ctrl-right loads the next screen of data pretty much instantaneously. I'm using trunk, but I don't see any recent changes which should affect this.

I also don't see this.  Can you re-confirm?

Comment 3 Nicolas Brisset 2007-02-14 18:35:03 UTC

Let's close this, it seems to work now. I must have had a broken build at some point...
