It's a part of idutils package, devel/idutils.  This mkid
parses all .c, .h, .s files and creates a tag file named
'ID'.  It is not a benchmark program but it acceses files
and it spends about 10 secs once files are cached on 512M
memory allocated for DomU.  I'm not sure it is suitable to
evaluate the system or not for our case, though.  It was
just handy.
