Output from the test itself is redirected to file on disk (SSD 100Gb INTEL SSDSA2BZ100G3 6PB10362). Results was checked from remote ssh session. (In reply to Eugene Grosbein from comment #17) I have switched MSI-X support off in one of the previous attempts to solve = this issue. Actually, it doesn't change anything at all in my test case. ------------------- OK, current results from still-running test: Computer A1: root@fspa1:~/clock/new_res # grep times periodic.txt | awk '{print $3 " " $= 4 " " $6 " " $8 " " $10;}' | sort | uniq -c 212603 send_sync 0 0 0 0 6437 send_sync 0 0 0 1 10 send_sync 0 0 0 229 4177 send_sync 0 1 0 0 1 send_sync 0 1 0 1 Computer A2: root@fspa2:~/clock/new_res # !459 grep times periodic.txt | awk '{print $3 " " $4 " " $6 " " $8 " " $10 ;}' | sort | uniq -c 122102 send_sync 0 0 0 0 100857 send_sync 0 0 0 1 47 send_sync 0 0 0 2 12 send_sync 0 0 0 230 2 send_sync 0 0 0 231 170 send_sync 0 1 0 0 I have set kern.timecounter.fast_gettime=3D0 yesteday, on both A1 and A2, a= nd for last 12 hours 6 more cases of long delays appear on A1, and 8 on A2 compute= r.
