When you enter LV you'll noticed that, for certain things like forgehammer's Steam Multiblock, simple washer or really any super fast machine, the 20 seconds between stacks of LV conveyor modules are awfully slow.
If you want to solve this issue and don't mind of using a little zinc and Steel for some filters: as soon as you have access to an assembler you could use Filtered conveyor modules, Filtered conveyor modules move items at a wooping speed of 1 stack every tick.
Some issues are that if you want to switch between import and export you'll need to use a crowbar and Craft the other mode in your inventory (import → export and vice versa) and you could acidentally activate the filter by rightclicking with literally every item, to solve this just change the mode in the module settings from whitelist to blacklist for this to not be an issue.
