|

In some situations Linux may deliver a better write performance to drives if
|
||||
the track input is read with O_DIRECT (see man 2 open). The included libburn
|
||||
and the cdrecord emulation of xorriso can be told to use this peculiar read
|
||||
mode by:
|
||||
--enable-track-src-odirect
|
||||
|
||||
But often libburn will yield even better performance in such a situation if
|
||||
64 KB are transmitted in each write operation rather than 32 KB.
|
||||
64k can be made default at configure time by:
|
||||
--enable-dvd-obs-64k
|
||||
This may be combined with above --enable-track-src-odirect .
|
||||
|

If you want xorriso to report a "Build timestamp" with its option -version:

||||
make buildstamped
