McMasterCarr gives a gallons per minute for their socks. It labels it MAX flow so I would think that is for their 200 micron socks since it includes all micron sizes.

The size of the bag (length and diameter) will make a difference in the time between cleaning. Larger bags have a greater surface area and therefore will flow more and collect more particulate matter before needing to be changed.
I am currently running a 7"x16" 100 micron sock and I can go about two weeks between changes flowing 700 GPH.
Going up in diameter will give you a larger relative increase in area. A 7" sock has about 3x the surface area of the same length 4" sock, so it should last about 3x as long between changes. A 32" sock only has 2x the area of a 16" sock of the same diameter - plus a 32" long sock gets rather unwieldy to set up, I would think.
I am fairly new to filter socks, so I certainly am no expert, but I put quite a bit of thought into it before setting up.
One question I have is about how everybody hangs theirs - hanging in air, submerged, or partially submerged?
Below are a few photos of how I set up my filter sock. I plan on replacing the bucket filter in the back of the last photo with another filter sock, but I haven't gotten around to it yet.
