I can't. Having the same problem, but my computer is too crappy for 10 render distance.
There is a bug in Minecraft that significantly reduces hostile mob spawns with short render distance. If you can't turn your render distance up to 10+ you are simply out of luck, as that bug has existed for a long time and likely isn't going to be fixed any time soon.
