I noticed that any change to vm.dirty_ratio causes write throuput to plummet -- to around 5Mbyte/sec. <system bootup, kernel 4.0.5> # dd if=/dev/zero of=/path/to/file bs=1M # sysctl vm.dirty_ratio vm.dirty_ratio = 20 <all ok; writes at ~150Mbyte/sec> # sysctl vm.dirty_ratio=20 <all continues to be ok> # sysctl vm.dirty_ratio=21 <writes drop to ~5Mbyte/sec> # sysctl vm.dirty_ratio=20 <writes continue to be slow at ~5Mbyte/sec> The test shows that return to the previous value does not restore the old behaviour. I return the system to usable state with a reboot. Reads continue to be fast and are not affected. A quick look at the code suggests differing behaviour from writeback_set_ratelimit on startup. And that some of the calculations (eg. global_dirty_limit) is badly behaved once the system has booted. The system is an HP xw6600, running i686 kernel. This happens whether internal SATA HDD, SSD or external USB drive is used. I first saw this on kernel 4.0.4, and 4.0.5 is also affected. It would suprise me if I'm the only person who was setting dirty_ratio. Have others seen this behaviour?
