What to do about slow query log in MariaDB?
As a significant number of queries can run quickly even without indexes, you can use the min_examined_row_limit system variable with log_queries_not_using_indexes to limit the logged queries to those having a material impact on the server. It can be beneficial to log queries that examine a minimum number of rows.
How long does a MariaDB query take in MySQL?
On the old server with MySQL 5.5.50 the query takes around 8 seconds to complete. On the new MariaDB 10.3 it takes well over 22 seconds (!!!), and I can’t figure out why. If anyone of you could help me to understand why such a huge difference in performance, please, let me know.

How long does it take to insert 10.000 rows in MariaDB?
The result for inserting 10.000 rows is 0.13sec on the old computer and 8.5 seconds on the new one. Just to be sure it’s not the SSD or something I wrote a same testscript only using SQlite3 this time and insert 1.000.000 rows in just 7 seconds, so it is only MySQL and MariaDB only.
How is MySQL performance compared to MariaDB performance?
Some additional info: when executing the script, the SSD is having 0% load and the CPU has about a 30% load. Reinstalled Wamp 3.2.3. Tested it with MySql 5.7.31, 8.0.21 And MariaDB 10.4.10, 10.4.13, 10.5.5. There is a difference of a few seconds here and there, but still slow.
Why is MariaDB so slow on Windows 10?
So what else I’m missing here? Some additional info: when executing the script, the SSD is having 0% load and the CPU has about a 30% load. Reinstalled Wamp 3.2.3.
Why is MySQL Query slow under certain conditions?
I am having a strange issue with a slow query under certain conditions: I have made a few tests and was able to isolate the issue to one single table called products_description (all the tables are MyISAM). At first I noticed that when this table is new (ie. just imported), the query always performs fast (~0.3s).
What’s the difference between MySQL 8 and MariaDB 10.4?
For example, MariaDB 10.4 has INNODB_MUTEXES to expose “SHOW ENGINE INNODB MUTEX” in a table format which is easier to extract and report rather than parsing strings. MySQL 8 does not have an INFORMATION_SCHEMA.INNODB_MUTEXES table.
