How to slow down a particle effect

I have a smoke effect, but it is shooting from it's emitter really quickly and I'd like it to go a lot slower (so it's more floating along rather than being propelled at high speed). I tried right clicking the effect and going to 'set speed' and halved the speed, but all it did was make the effect longer and not slow it down at all. I definitely clicked 'set speed' and not 'set duration'.

Set speed is for video clips, not for effects that are being dynamically created. The speed of the particles is controlled in the Particle Attributes, along with all other aspects of the effect. You need to open the speed gradient and turn down the speed of the particles. Its the horizontal bar just by the Speed Randomizer slider. Double-click it to open 'er up, and turn down the speed if you want the particles to go slower.

I've been trying what you said to do, however all it is seeming to accomplish is making the individual particle shapes either more spread out or bunched up together, but the actual movement of them is not going any slower. I am double clicking on the horizontal box directly above the 'Speed: Randomizer' slider and then it comes up with a window with various points on a graph that can be changed to go higher or lower. Is this the window you are talking about?

As long as its titled Speed Gradient, and not Color Gradient, that's the one, yeah. Select each anchor point and turn down the speed, you can go down to like 1/10th of a pixel per frame, or something like that, which should move pretty slow.
You may also want to check the Gravity controls and see if there is a gravity force pulling the particles in any direction. That will increase their speed.
