Product Export Vert Very Slow


We are trying to export products as a CSV via datafeeds as we need to export specific data points that the standard product exporter doesn't support

We have around 50,000 products but the exporter is insanely slow. After 12 hours it had only exported about 40%. It's only roughly 5-6 rows of data per product and we are using MyCloud ultimate hosting

Have tried to purchase CS cart support but there is no purchase button on the support packages, which doesn't fill me with a lot of confidence for an E:Commerce platform development house

Has anyone else had this issue?
