I think bassists overuse rosin, generally, to compensate for not using their weight effectively. Yes, there is a "rosin-y sound" that is currently popular in America especially, but most people use so much rosin I can't even use their equipment.
With a little bit of practice you can make one bow stroke last 45 seconds or more (there was a violinint who claimed 2 1/2 minutes per bow?).
[...]
However, to play expressively with phrasing you have to also control varying the speed and dynamic within the length of bow strokes. The basic tools at our disposal are obviously Bow Speed, Bow Weight and Distance of Contact Point from the Bridge but that is only the start of a long journey with lots of experimenting to do. Somewhere to begin is what I believe is called Solfege (correct me if I am wrong please). There are six basic exercises (or more?) for you to examine -
(1) Down bow starts slow and soft then accelerates to fast and loud, adding in a little more weight to control the string vibrations. Returning up bow does the same. The effect is most dramatic if both the other variables are added in, increasing weight and moving the contact point.
(2) Loud - soft, loud - soft with alternate bows
(3) Soft - loud on the Down bow going to Loud - soft on the Up bow (the more common "hairpin" sign?)
(4) Loud - soft on Down towards Soft - loud on Up (the reverse)
(5) Soft- loud - soft in one bow followed by the same in the next.
(6) Loud - soft - loud connecting to loud - soft - loud (the reverse)
Many hours of happy hunting and keep safe!

I think the 2 1/2 minute bow was Galamian! That's a claim I've heard before. Having worked with some students of his (and students of his students) I'd believe it. It looks like a statue practicing Tai Chi.
To add to these good exercises that David has supplied, I'd also recommend something my HIP bass teacher had me do.
F major scale, 2 octaves, 60bpm. start with a double whole note (8 beats), and then progressively use smaller intervals ( dotted whole, whole, dotted half, half, quarter etc) up and down the scale. Sounds simple, right? here's the trick -
Use the whole bow for every note.
You learn a lot from this exercise. How to use a faster bow with good sound, sure, but also how to just move from one end of the bow to the other quickly. You also learn that not all the sounds you use in practice will end up in the performance - using a whole bow for an eighth note is a very specific sound that is basically never called for in any setting, but knowing how to cover that distance is really useful for retakes and learning how to plan out your bow length (i.e how much bow to use for each note).
Going back to the original post, your bow speed SHOULD vary, but it should vary in the right places and for the right reasons. "Oh crap I'm running out of bow", and "oh crap I need to get back to the frog" are just not good reasons!
