I can verify that this is indeed an issue on my windows machine (work computer).
If I select 1 artboard to export it is done straight away, as soon as I select 2 or more, there is an exponential increase in the time it takes to export each artboard.
On my home computer which is a Mac, it can export 16 artboards in a few seconds compared to about hour for the Windows machine. It was around 3 hours for 100 artboards or so.
