File Format of the Profile Output File
This section documents the format of the profile output file. All strings and numbers are stored in the Java binary format. Numbers (2-byte integer, 4-byte integer, and 8-byte IEEE floating point) are all stored MSB first. Strings are stored as a two-byte number of bytes, followed by the string itself encoded as UTF-8.
The general format of the file is:
Node info blocks
Graph info blocks
There are a number of places where a profile count is written. This simply refers to an unsigned four-byte integer number of iterations, followed by a double representing the number of seconds.
