Logfile Analyzer import / Performance

Hi,

obviously Piwik is not very fast importing apache access log files.
I tried to import a 350 MB access.log and after 8 hours import_logs.py did not finish yet.

I wonder what happens when you stop the import_logs.py process and start it again (with exact the same parameters).
Does import_logs.py "recognize" how many lines it already imported in order to continue with the rest?

Thanks and best regards
