Sync file on write?
Hi, I have a USB device and write speed is terrible when I copy more than 1 file to it (it is mounted in async mode). If I copy just one file and sync, speed is 17MB/sec, if I copy more than 1 file the speed drops well below 2MB/sec. This does not happen on MS Windows so I think it's some side-effect of linux i/o flushing creating multiple write-streams or something like this. Anyway, I'm trying to work-around this and wonder if there is a way I can tell MC to sync/fsync (whatever means ensure file is written to disk physically) after each file? If it would apply only to writes into this device that would be even better :) thanks paul ___ Mc mailing list http://mail.gnome.org/mailman/listinfo/mc

I am not a specialist in Midnight Commander to any extent whatsoever. I do know a bit more about USB, but I have never delved very much into questions of speed. Keeping the above disclaimers in mind, it does appear to me that there is a simple test which might help to localize the problem. Can you set up a situation in which the slowdown occurs in Midnight Commander, but it is possible to move the same files from the same source location to the same destination using command-line tools only? And run a time comparison under both circumstances? Theodore Kilgore ___ Mc mailing list http://mail.gnome.org/mailman/listinfo/mc

Theodore Kilgore Hi, Sorry if I wasn't clear, the problem isn't caused by MC and I don't think MC has anything to do with it, but it is simply my tool of choice for everyday working. It happens if I use cp from command-line or copy files from within MC or using GUI tools. In other words, this is slow: cp file1 file2 file3 /mnt/usb; sync this is fast: cp file1 /mnt/usb; sync cp file2 /mnt/usb; sync cp file3 /mnt/usb; sync So that's why I was curious if there's any kind of after file command or option to make it sync to disk after every file.

Interesting. So, what you are saying is, it is possible to change things on the command line so that it works fast. But if one uses the obvious construction of the command there is a slowdown. So if there is a problem with using Midnight Commander the problem is that, underneath, MC is using the usual tools in the usual and obvious way instead of clevering itself around the problem. Which I would tend to agree is not a shortcoming of Midnight Commander, per se. It is after all one of the things that I use, too, as a tool of choice for everyday working, or else one would not find me subscribed to this list! Quite seriously, why don't you bring this question to the attention of the people on this list over here: usb-stor...@lists.one-eyed-alien.net I think some of them might find that your experience raises an interesting question or two. Me, I also wonder exactly what is behind the problem. Come to think of it, though, what happens if you are not copying to or from a USB flash drive? Do similar things also occur if you are copying between two internal hard disks, or from one place on the disk to another? If that is the case, then this is not a USB storage problem after all, is it? Theodore Kilgore ___ Mc mailing list http://mail.gnome.org/mailman/listinfo/mc

For the Dutch translation I was apparently just in time for the release :), but if I had known the release of 4.7.0 was so close, then I would have taken a second look if everything was alright (and I already spotted some bugs in nl.po). In general, we try to release at least a beta release every two month with stable releases every 4-6 month or so. If you'd like to check what is the currently planned next release date, you can follow the roadmap on trac. Either way, next time we will send out a reminder to the translators about two weeks before the next planned release date. Thanks, that reminder would be welcome. +1 -- Marco Ciampa ++ | Linux User #78271 | | FSFE fellow #364 | ++ ___ Mc-devel mailing list http://mail.gnome.org/mailman/listinfo/mc-devel
