A huge pile of packages doing nothing shouldn't create any lag
Imagine a server.
Filled with at least 50 weapons each with their own package for the light AND trigger commands.
Now, imagine that server with 50 people, each firing at a rate of a simple 10 bullets per minute, and each using the light key to reload around once a minute.
That's over 458 function calls per second.
Raise that bullet rate to 30 bullets per minute, and you have to raise the reload rate to around 3 times per minute.
That's
1,375 functions calls per second. And when there's a large battle going on, that can raise upwards of 2300 function calls per second.
For torque, that's a damn lot to handle.
