Query execution speed is an important aspect to consider when picking a database, but by no means the be-all and end-all for most applications' needs. Your page is incredibly light on details about what the product can and can't do which makes it impossible to evaluate whether it's worth my time to install it (which I can't anyways since I don't have a Windows machine) and look. If a database product website can't tell me basic things about it like: does it support transactions? What SQL syntax is supported? Is it row or column oriented? What wire protocol is used and what clients are supported? It makes it difficult for me to imagine where the product could be useful.
