$ xpra -h | grep mmap=
--mmap=yes|no|mmap-filename
So you can use:
xpra start --mmap=/the/server/path
xpra attach --mmap=/the/client/path
And make sure that both paths resolve to the shared area where mmap
files can be created.
This may well require changes to the IPC settings in your container tool
to allow mmapped files. YMMV.
The difference in performance is huge, so it is worth doing.
