Re: MariaDB-10.2.11 Long Time To Start


Hi Michael,

OK, all the interesting functions (InnoDB functions) are displayed as ??.

In the "perf top" it would have helped to drill into the mysqld executable,
and only show its top functions. Apparently a lot of pages are being read;
that is all that I can tell from the screenshots.

Can you try the following:

1. Find the proces ID, e.g., ps ax|grep mysqld
2. gdb /usr/sbin/mysqld
set log file /tmp/gdb.txt
set log on
attach [pid]
thr a a bt

With this we should get detailed stack traces. I am interested in the
thread whose stack trace includes plugin_init and mysqld_main.

​Could you please try again?
