CubaApplicationServlet - Too long request processing [6539 ms]: ip=0:0:0:0:0:0:0:1

Hello,

I developed a new project (Cuba 7.2.3), I have a small test PostgreSQL Database and randomly I have this error when I start the application:
CubaApplicationServlet - Too long request processing [6539 ms]: ip=0:0:0:0:0:0:0:100:

I looked in perfsat-ui.log and I found:
MenuItem_Transaction.browse 6306.0 6306 6306 (ms)

Also I activated eclipselink.sql at DEBUG level and I have a lot of such kind of lines:
2020-07-03 10:27:52.669 DEBUG [cuba_core_scheduler-7/myapp-core/admin] eclipselink.sql - <t 391136360, conn 570841087> [5 ms] spent

AND (DELETE_TS IS NULL)) FOR UPDATE
bind => [true]

What should I do from now on?
