Firing speed - bug or intended?

[SonicB]

Coming back to the game after a fair few months, I've noticed that the game still doesn't like too many guns firing at once. If you have multiple fast-firing secondaries active, it takes much longer to complete a main battery broadside - sometimes some turrets just fail to fire.

Turn off secondaries and the broadsides fire as intended.

This also seems to affect heavy secondaries, for instance a mixed secondary battery of 6" and 3" will experience much slower 6" fire rates when the 3" are active.

I flagged this several months ago, and a year before that, never got a dev response. Could I get a final answer if this is intentional or is it on the list to be fixed?
