Hi all, I'm running an instance of OBS 2.9.3 with two workers, building all sorts of stuff including kiwi images. Sometimes, it takes very long to upload the build results. Right now, the worker is uploading an image, which finished build at 09:21: # ls -lh /srv/obs/worker-root/root_9/.build.packages/KIWI/SLES_12SP2_SAAS_VM1.x86_64-2.4.0-Build3.1.tbz -rw-r--r-- 1 root root 457M Jun 27 09:21 /srv/obs/worker-root/root_9/.build.packages/KIWI/SLES_12SP2_SAAS_VM1.x86_64-2.4.0-Build3.1.tbz obs:~ # l /srv/obs/jobs/x86_64/.putjob.17789/SLES_12SP2_SAAS_VM1.x86_64-2.4.0-Build3.1.tbz -h -rw-r--r-- 1 obsrun obsrun 88M Jun 27 12:31 /srv/obs/jobs/x86_64/.putjob.17789/SLES_12SP2_SAAS_VM1.x86_64-2.4.0-Build3.1.tbz As you can see, it's three hours for 88MB... a bit slow for a multi-gbit ethernet link ;) stracing the worker process, I see it sending packets: 12:39:37 read(5, "\16\245\0Y\fEw\237M\16\367\227\30}\265'"..., 8192) = 8192 12:39:37 write(4, "2000\r\n\16\245\0Y\fEw\237M\16"..., 8200) = 8200 12:39:42 read(5, "\342\233\332\370\36W\331\177g=\272\337pbll"..., 8192) = 8192 12:39:42 write(4, "2000\r\n\342\233\332\370\36W\331\177g="..., 8200) = 8200 and the 5 seconds pause in between looks like it might be some missing tcp flag, or timing parameter or such? this is my iperf summary for this link: [ ID] Interval Transfer Bandwidth Retr [ 4] 0.00-10.00 sec 6.82 GBytes 5.86 Gbits/sec 0 sender [ 4] 0.00-10.00 sec 6.82 GBytes 5.86 Gbits/sec receiver So the network itself should be fine. Any hints how to debug that?
