Lags in 1.9 (Snapshot) with Commandblocks

Tested in new world and old world.
Problem happens earlier in old worlds.

I tested it with this Command:

/particle happyVillager ~ ~5 ~ 0 0 2 0.01 10

Commandblock is in repeat-mode (activated via Redstoneblock).

In old worlds you need only 5 Commandblocks running this or any other Command like /testfor @e - in new worlds it needs up to 20 Commandblocks.

It needs vom 30s to 5 min to have those lags.
When the lags appear Mobs seem to be in slowmo.

commandBlockOutput is false

Please attach the complete output of the "Game Output (Your Minecraft name) " which can be found on the fourth tab of the launcher to this ticket.

If the launcher closes after game start, please edit your profile and select "Launcher visibility" then, "Keep the launcher open".

OK, done - funfact: this time it was al little harde to reproduce the situation. It seems i am not the only one, who experience this issue. Hope Mojang will fix this, otherwise Adventuremaps and Server with some customization are history. This would be realy bad.

Outdated graphics drivers. Please update to 361.43.

I don´t get it - why is my issue a duplicate of this MC-90683 It has nothing to do with this issue. I killed the Armor Stands now an the Problem still occurs. It is definitely not the same issue.

Have added a new game-output-report, where the Armor-Stand-issue is solved, but my Problem with those lags ist not.

New Crashreport also added. Same Issue as in first.

The Commandblocks are definitely the source of this issue, not some Problems with entities riding entities!

Reopened.

Confirmed in 16w02a.

@unknown no need to comment, you're the reporter and can update the affected versions yourself

Still a problem in 16w04a. Sure wish this would get looked at.

I think this is tied to another ticket (#MC-94438). I don't see lag on worlds with no mobs, even with hundreds of repeating command blocks (not that these are particularly interesting worlds).

migrated

It seems like Command-Blocks, which are running do make this problem much faster visible (the lags occour earlier), so yes my problem may relate to 94438.

seems fixed with 16w07a
