Yeah, it's global currently.
Small benchmark on a 4core Xeon on a 416MB pcap. Debug and unittests and
all kinds of other crap still compiled in. Streaqm depth and http body
tracking but unlimited.
files log enabled, md5 forced: 6.8 sec.
files log enabled, md5 disabled: 6.8 sec
files log enabled, md5 not compiled in: 6.6 sec
Log contains 11088 file records.
