Correction: I'm still seeing the slowdown. I created two test cases: one for the fake file I showed you and one for my real data. All I do is grab a value from the first block and return a string. Both files are similar in structure and size (1.5 real vs. 1.1 fake). For some reason, the real data has a pause and the fake doesn't. This is very weird. Any thoughts on why this would be happening?

FYI: I'm using the REST interface, so my code looks like this:

string postSample(Json block1, Json[] block3)
{

  return block1.val1.toString();

}

Is there a way for me to turn on code coverage to see where the delay may be?
