Hi Marko, Kinda outside of my element here, but attached are a few screenshots from perf top -g Thanks, Mike On 2018-01-08 10:34 AM, Michael Caplan wrote:
Hi Marko,
I can reproduce this reliably with every start up.
Poor man's profiler output:
84 ../sysdeps/unix/syscall-template.S: No such file or directory. 10 ??,??,??,??,??,??,start_thread,clone 5 at,??,??,start_thread,clone 1 pread64,??,??,??,??,??,??,??,??,??,??,??,ha_initialize_handlerton(st_plugin_int*),??,plugin_init(int*,,??,mysqld_main(int,,__libc_start_main,_start 1 at,??,start_thread,clone 1
Anything else I can get you?
Best,
Mike

Hi Michael,

This is really unacceptable behaviour. It looks like you have encountered https://jira.mariadb.org/browse/MDEV-9843 where this exactly same behaviour has been documented.
Can you reproduce the delay on every startup? Stack traces (from http://poormansprofiler.org/ or "perf top -g" or similar) during this startup delay would be very useful.
With best regards,
Marko
