Dear all,

I’m having problems with both 0.9.24 and 0.9.18 versions of Demeter. When I open a new file, just after starting Athena, both versions work well, but as soon as I start to do something, e.g. deglitch a curve, the program starts to become very slow. This means that to choose a point on the graphic it take few minutes. I checked with the task manager and it seems that at the beginning gnuplot is using about 10% of CPU, but then it raises and it uses at maximum 25% of CPU, it does not go beyond this value. The CPU affinity is set to 4 CPUs, but it seems gnuplot uses only 1 (25%). If I close the program and restarted it, it happens the same. I’m using Windows 7 Enterprise, Service Pack 1, on an Intel Core i5-4590 CPU@3.30GHz (4 CPUs), with 8GB RAM.

I use gnuplot out of the box and with no modification from how it is delivered. There is no plotting task in Athena that should take gnuplot more than a second to complete using a single core on a reasonably modern computer. When plucking a point from a plot, there is a built-in delay that should be, at most, 10 seconds. Usually much less. I have certainly never seen the behavior you describe. I am away from my office (and so away from any windows computers) so I cannot look into it right now. Is there any chance that your anti-virus software is interrupting gnuplot's operation in some way?
