Can someone please help me here?
Are you planning on porting this to Python3 ?
Pantastic seems to be a fantasic piece of software! But I benchmarked it a little bit, and noticed that if it's scanning some very large file(s) (like 10GB+) the Python process uses RAM as much as the file size is. Is that correct, or did I misanalyze it?
I think it would more efficient, if it reads the file in 128KB to 100MB chunks (maybe that could be even configurable parameter), instead of reading the whole file in RAM at once. Or if it does that chunk based reading already, maybe it should free up the used memory immediately after it has scanned that particular chunk (before reading the next one). Of course, in that case, some last bytes from the previous chunk need to remain in the RAM if the PAN is split between two chunks.
