Way too little information to go on here. What is the hardware in the two different systems? What version of the OS (64-bit/32-bit), what is the network to the database server from the two computers?

Have you debugged at all (debug on the slow machine, hit the pause when you notice the delay, see what line its on)? There are additional things here that we can't see or know to make a good answer for you.

Check event viewer. Trace it. We can't see anything so there's no way we can know.

Not a question. There is no a common recipes. Time your code, find out bottleneck, etc...

Please see my comment to the question. Time fragments of your code to find bottlenecks. For timing with very good accuracy, you can use the class System.Diagnostics.Stopwatch, for logging — the class System.Diagnostics.EventLog:

http://msdn.microsoft.com/en-us/library/system.diagnostics.eventlog%28v=vs.110%29.aspx[^].

Consider finding and using some code profiler: http://en.wikipedia.org/wiki/Profiling_%28computer_programming%29[^].

If, with all your improvements, application start up it still too slow, use some splash screen: http://en.wikipedia.org/wiki/Splash_screen[^].
