Hi Juerg, This is of course a possibility but I tested it at the setup time and right now:
sudo hdparm -t /dev/sda /dev/sda: Timing buffered disk reads: 442 MB in 3.00 seconds = 147.14 MB/sec sudo hdparm -t --direct /dev/sda /dev/sda: Timing O_DIRECT disk reads: 450 MB in 3.01 seconds = 149.73 MB/sec This is consistent over 10 tests, lowest value was 141 MB/sec (all other services running). The fact this happened after an update twice in a year, corrected after some weeks the first time, is a clue. I see some similarities in this topic https://github.com/raspberrypi/linux/issues/4133 but as it's not a major topic the root cause should be specific to some setup or conditions (a guess) ** Bug watch added: github.com/raspberrypi/linux/issues #4133 https://github.com/raspberrypi/linux/issues/4133 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1962180 Title: Samba performance degraded after last update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/1962180/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
