I've personally never seen any log splitter under 11 gpm, that's pretty much bottom-of-the-barrel 12 seconds on a 4" cylinder level DIY'er stuff. More common around here is 16 - 23 gpm.Small splitters have pumps rated at 2 to 3-gpm. Splitters with larger rams, typically have 11-gpm. Big splitters have 16 to 20-gpm. If your tractor is a 23 to 25-hp CUT, you probably have 3 to 5-gpm. A 35-horse tractor will be around 11 to 15-gpm.
I can't understand any advantage in running a log splitter off tractor hydraulics. It's a slower and less convenient way to accomplish what can be done with a 10 hp Honda, Subaru, or Intek engine, ubiquitously available for a few hundred dollars. Better keeping the tractor free of the thing, for moving logs, rounds, or splits around, and putting all those hours of idling away on a much cheaper engine.
That said, if I were going to run a splitter off my tractor, it'd be closed-loop with a PTO pump. Way faster, as most CUT's can deliver much more HP thru the PTO than thru auxiliary hydraulics. Also keeps the systems segregated and clean.
