I get a 1 second time for the first run and then a much quicker time for the second. I did some sampling and the longer time due to is Apple’s check for malware on first run of a process. This is a known, documented and advertised behavior. It is a one time cost and only effects applications, not regular files. For a developer though, yeah you get the cost after ever rebuild. So I don’t think this test is analogous to your initial issue of a delay opening a file every time.

Would you mind posting the bug number?
