Setting 'so' to false had unfortunately no effect for this (very synthetic)
>> tic(); plotdecimate([(1:125000)' (1:125000)'],'false'); toc();
Elapsed time is 153.31 seconds.
>> tic(); plotdecimate([(1:125000)' (1:125000)']); toc();
Elapsed time is 152.986 seconds.

When trying the same with some real measurement data (size 125000 x 2), the
effect is also negligible:
153.196 seconds / 153.524 seconds
