I am not generally happy with what they say in their benchmarks section
either. But we all know how rigged benchmarks generally are.
According to their documentation site, they haven't released a product
in almost 2 years (before they were releasing every couple of months).
Not sure yet, but it seems that development has ceased? This doesn't
look like a good sign. So is it really worth hassling them over this?
Best Wishes,
