bullets,bullets,bullets! performance goes RAAWH

my game contains a lot of projectiles(slow projectiles,not the rifle type of projectiles) which seem to be causing a lot of performance problems since every action with a projectile is multiplied by the number of projectiles.for example, i check each projectile for collision with the world every frame. i already divide the world into regions,so if i have 100 projectiles in the game,that's 100 "Which region to check" checks,and another 100 checks minimum considering there's at least 1 object in each region.the problem here is that every small action that i do with a projectile,is multiplied by the number of bullets and causes some serious performance problem. and i really prefer finding a solution to increase the performance checks here rather than reduce the number of projectiles.is there any kind of optimization suited for a situation like this?
