It’s not just block mining that a low tps will impact, but all factors of the game. Such as furnace smelting times, crops growth, mobs, etc

Low tps is most common in modded, but can also be an issue in non-modded, and can be caused by a number of factors.
In base Minecraft lots of hoppers, droppers, and big Redstone contraptions can all cause tps issues. Along with lots of ground items, or mobs
