When punching trees (especially with powerful tool) game becomes extremely laggy. Turning off 'advanced opengl', turning graphics quality from fancy to fast and turning off advanced lighting helps a bit but process still stays very laggy.
Also being in vicinity of large quantities of leaves creates some slowdowns.

The lag do not depend on render distance and stays same on different distances set. Powerful tool - in example efficiency axe. Not using mods.
Game runs very fast - 40-60 fps everywhere (even in nether, even with fancy lighting and advanced opengl it stays 20+ fps) - only when getting close to large amounts of leaves it goes to 20 fps. Starting punching trees gives a lag 2-6 fps.
Anywhere else it goes 40-60 fps - fighting large amounts of mobs, running fast large distances, even setting a lot of fire or detonating lots of TNT it goes well.
Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
It was still a concern 1.4.5 but I upgraded my hardware since then and I can't check this out again any more.
In this case I would have to assume the lag is mainly due to your system specs. How far do you have your render distance set? What do you define as powerful tool? Do you have any mods (ex Optifine) installed?
