Hello Amudhan,
What does exactly mean "it takes < 250KB/s"?
I figured out this discussion between you and Kotresh: https://lists.gluster.org/pipermail/gluster-users/2016-September/028354.html
Kotresh mentioned there that the problem is because for some files fd process are still up in the brick process list. Bitrot signer can only sign a file if the fd is closed.
And according to my observations it seems to be that as bigger a file is as longer the fd is still up. I could verify this with a 500MiB file and some smaller files. After a specific time only the fd for the 500MiB was up and the file still had no signature, for the smaller files there were no fds and they already had a signature.
Does anybody know what is the reason for this? For me it looks loke a bug.
Regards
David

Hi David,I have also tested the bitrot signature process by default it takes < 250 KB/s.regardsAmudhan POn Fri, Mar 1, 2019 at 1:19 PM David Spisla <spisla80@xxxxxxxxx> wrote:_______________________________________________Hello folks,I did some observations concerning the bitrot daemon. It seems to be that the bitrot signer is signing files depending on file size. I copied files with different sizes into a volume and I was wonderung because the files get their signature not the same time (I keep the expiry time default with 120). Here are some examples:300 KB file ~2-3 m
70 MB file ~ 40 m
115 MB file ~ 1 Sh800 MB file ~ 4,5 hWhat is the expected behaviour here?Why does it take so long to sign a 800MB file?What about 500GB or 1TB?Is there a way to speed up the sign process?My ambition is to understand this observationRegardsDavid Spisla
