SonicWall brakes WEB interface, is this normal?

Question

Computer networks

began to work closely with the SonicWall hardware, via the WEB interface, because I find the console very inconvenient.
But! You have to wait 3-8 seconds for the interface to react to each click.
I had previously dealt with this equipment (different models in different companies) and, in general, the brakes were the same, but because It happened sporadically, then it did not create any problems.
How can I make it work properly?
