Dealing with slow performance of "Resolve links" in dictionary import
Dictionary import hangs on Resolving links for a while even if file contained only several Concepts.
Solution
Problem can be related to MySQL performance after upgrade, to resolve it you need to run optimization tasks, next is an example of mysqlcheck
command which is coming with every mysql client or server:
mysqlcheck -h localhost -u admin -p --auto-repair --all-databases
mysqlcheck -h localhost -u admin -p -o --all-databases
replace localchost
with url of your database, admin
with name of your mysql administrator user
Or you may find similar functionality in your favorite DB managing software, like DBeaver, phpmyadmin, MySQL Workbench, etc.
