Hi, for some reason i did not get the last two mails from Leandro. Only good that George brought me back to the topic.
I propose to next explore libisofs without a burn process being involved. If Brasero can burn to a disk file as "drive" target, then try whether it is as slow as with optical media. Another test would be to install xorriso. E.g. by apt-get source libisoburn or from source http://scdbackup.sourceforge.net/xorriso-0.4.8.pl01.tar.gz build by: tar xzf ..../xorriso-0.4.8.pl01.tar.gz cd xorriso-0.4.8 ./configure make make install (or execute as ./xorriso/xorriso) One my run it by its mkisofs emulation xorriso -as mkisofs -o /dev/null \ -R -J \ file_or_dir_1 file_or_dir_2 ... which will tell no speed numbers. Or by its own CLI xorriso -outdev stdio:/dev/null \ -add file_or_dir_1 file_or_dir_2 ... which will give a progress report with DVD speed measurements xorriso : UPDATE : Writing: 3257s 0.5% fifo 0% buf 50% xorriso : UPDATE : Writing: 20875s 3.0% fifo 0% buf 50% 62.7xD ... xorriso : UPDATE : Writing: 664063s 96.8% fifo 0% buf 50% 56.4xD ISO image produced: 685604 sectors This is on a 3000 MHz AMD. About 20 times faster than you experience with Brasero. If this works fast, then you should try a dummy run with DVD-R: xorriso -outdev /dev/sr0 -dummy on \ -add file_or_dir_1 file_or_dir_2 ... If any of the xorriso tests is slow, then i will have to invent a theory and some experiments to verify it. (Any hint is welcome then.) If they all are fast, then one will have to search the bottleneck in Brasero. Have a nice day :) Thomas -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
