Comment 1 for bug 991930

"Thousands" is really not a lot of tests, unless you mean "hundreds of thousands." So, if it's only a few thousand, you should look to the nature of the tests themselves - for example, how you generate data for the tests - for a solution.

For NUnit 3.0, we will move to loading on a separate thread, which should show some improvement. We also expect to implement dynamic test cases, where the data is only generated when the test is executed and not at the time of loading.

Both of those changes are out of scope for NUnit 2.x, so i'm redirecting this bug to the 3.0 project.
