I've followed a lot of suggestions for optimizing graphics performance, and my projects currently sails along quickly and lightly in terms of rendering.
I do, however, have some overhead on loading that I'd like to minimize if possible. It comes down to reading a text file of objects and coordinates (this approach is questionable, but let's stick with it as a given).
I'm reading in a file that contains a subset of lines I'm interested in ("MARK" being the intial characters). Then, only a subset of these lines, I want to store coordinate information for - I check for the existence of the line type using a single character from the line string in a hash I populate at the start of the code.
I'm using builtin arrays for everything below.
I have the following:
I'm clocking about 200 lines read per second. I'm wondering if anyone sees anything in the above code that could be streamlined for a time gain?
Cheers, and thanks for reading this far!

First thing i see - you're parsing the vectors twice each - store the intermediary vector, then use it for vec[i] and adding to vecSum
Second, you really should be using the overload of float.Parse that takes a CultureInfo object - otherwise on european computers, it'll have problems reading US/UK floats (and vice versa)
Third, you're printing two items each time - that'll slow you down ridiculously (it has to print the current stacktrace to a file, as well as displaying it in the console), so remove those if you're testing performance
