migrate from mysql to sql server express - concerns

Question

I have a desktop application which is distributable commercially. Currently I use MySQL as database but I read I need commercial license for MySQL each sale of my software.

So I am planning to move to SQL server express or MSDE as it is freely distributable. now why I am thinking about both msde and express is it says MSDE has a workload governor which has impact on performance. but express doesnt have it. Database size of 10 GB would be fine for me. 1 GB ram should be fine hopefully. but I'm a bit concerned about performance.

So would MSDE still be a choice? Would it be available in 2012 and further on?

A query in Express would be as fast as SQL server enterprise?

Is there any other factors I should consider ?

Answer 1

MSDE has been long discontinued, and SQL Server Express is a replacement for it.

I would be very surprised if SQL Server Express performance was inadequate for a desktop application, although who knows, maybe your workload has some special requirements? The best approach to be sure is to hook it up and give it some test workload and measure.
