--- Comment #11 from [email protected] ---
Have had time to figure out how to start the logging. Simple by typing this
SQL-command as admin:
SET GLOBAL general_log = 'ON';
Notice: All what I have tested I tested with MariaDB and no other client
connecting to MariaDB.

I notice
1) for every row a new query is started like this one:
SELECT * FROM "libretest"."Test" WHERE "libretest"."Test"."ID" = 11099
2) setting the table to last row only the last shown rows where queried
3) scrolling up from the last row it shows queries for the upper rows, but I
notice also queries for the last rows (as noticed in (2)) every time I stop
scrolling up. Don't know why the last rows are queried again and again.
Looking at the table scrolling will hang a little bit with (3).

I could send a query from Base through Tools → SQL - it is only one query for
all data I'm looking for:
SELECT * FROM "libretest"."Test" WHERE "libretest"."Test"."ID" < 100
shows all data in Tools - SQL and doesn't need more queries than only one.

Don't know why the GUI is designed this way. If there are many queries from
other clients it must be a performance-problem for MySQL.
I will set this bug to new. Changed also the system to all, because I have
tested with OpenSUSE. LO-Version here is 4.3.7.2
