PVsyst is very slow to respond to inputs-even loading a project or changing system parameters or details losses can take minutes to load the input screens. If I use a helios export for near shadings it is practically unusable- computing a shading factor table takes several days! The cpu usage seems to be low, and there is very little disk activity during these hang ups. What is going on? Every time I click something, I have time to go get a cup of coffee before the program reacts. Are there any tips to make it work better? I am using v6.39 on a laptop with 8GB ram, Core i-7 processor and a solid state hard drive.
