 Description   

My frame rate dropped while adding objectives to the scoreboard system.
I started with a frame rate of 160 per second after the 10th objective it slowly started to drop. I was not moving at the time, also there were no new chunks loaded, entities spawned or moved nor any redstone contraptions running.
After adding the ca. 15th objective the framerate was already only at 30. It dropped further while adding more objectives, at 20 objectives in a row it was only at two fps.
A relog helped both though, it got my frame rate up again and kept the objectives, still i wanted to report it, just in case.

No answer on querry, assuming no longer an issue.

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.

I added dummy objectives, sorry for not including that. It just comes to my mind that i also used the same displayName for around 15 of the objectives, since i needed different values for each players at once in one category.
An example "scoreboard objectives add s11 dummy Skill" with just the actual name varying from entry to entry.
When i reproduced the situation again, i noticed that the RAM usage of java didn't increase but the fps decreased anyway.

Weird! I can't reproduce, though. What kind of objectives did you add?
