As I said this requires 2 way comms, which is does involve both executables sitting in while sleep loops. I think I can fix this and I will look to do so asap. The line issue surprises me a bit. I will try to look at the cause.
To help you narrow down what the Linux issues are I just tested a pure ascii test case (the last 6 pages of example 23) and a pure line case (example 00 with the pllab call commented out, and the last argument to plenv set to -2 so absolutely no text is plotted at all by that example). and here are those results: Number cpu% idle% type of example modified 23 25% 75% pure ascii text with no graphics at all modified 00 20%* 80%* pure line graphics with no text So whatever the idle problem is seems to be roughly the same for pure text or pure line graphics. Furthermore, I put an asterisk by that second result because the first time I ran test_c_wxwidgets with 30 repetitions of the modified 00 example in plplot_test/test_c_interactive.sh.in, the cpu usage was effectively zero (at the background level) for each of the first ~25 repetitions or so. Essentially for each of these repetitions there would be a blip of cpu activity at either the start or end of the repetition but nothing else discernible on the graph for the relatively long times it took to finish each repetition. Then for the last 5 repetitions the idle issue went from completely horrible to merely bad (i.e., the idle% dropped from ~99 % to the 80% I state above). And then it stayed in that "bad" state for the next 30 repetitions I tried. Anyhow, because that modified example 00 is so simple with no text at all, that is the example I suggest you should investigate first for the cause of this clear idle issue on Linux that varies between completely horrible to just merely bad. :-) And if you cannot replicate that modified 00 idle issue on Windows, then it is likely time to attempt to verify it on the Ubuntu Linux box you have access to.
