Update man page:

-g Group output. Output from each jobs is grouped together and is only printed when the command is finished. stderr (standard error) first followed by stdout (standard output). This takes some CPU time. In rare situation GNU Parallel is taking up lots of CPU time and if it is acceptable that the output from different commands are mixed together, then disabling it with -u can speedup GNU Parallel by a factor of 10.

-g is the default. Can be reversed with -u.
