Touched event Delay...?

In my game, I am using the default Roblox Rocket Launcher tool taken from the Roblox Sets. When I use it online however, the rocket does not explode EXACTLY on touch, rather it explodes a few moments after it hits any part (The rocket goes through the part, and shortly after explodes) Is this lag? Or perhaps some flaw in the script..

I need the explosion to be instantaneous because I tweaked the script so that you will be able to rocket jump and such.

I have also added a way to detect collision using rays, and it works a bit faster better than the Touched event, HOWEVER, when I play on Solo mode (Test) in the studio, all the rocket jumps I commit and all knockbacks are perfect, and just as I wanted them to be, but when it comes to online, there's still that slight delay that can really screw you up, and completely makes rocket jumping impossible. Is there any way to get rid of this delay?

Thanks in advance.
