Current behaviour

After compiling using the https://github.com/trickerer/AzerothCore-wotlk-with-NPCBots/commit/4bdf5b7320e7874bb11232bfcfa17671ece8e302)version on June 29th, it was found that the CPU usage of the Worldserver process had once again increased. Under normal circumstances, when there were 5 online users, the CPU usage rate of WorldServer was around 30%, but it has now risen to over 80%.

At the same time, the last 500 diffs summary value displayed on the console has also significantly increased.

When normal the last 500 diffs summary value mean:12-15 median:11-12 percentiles:18,24,131

I am currently unable to determine whether this issue is caused by azerothcore or based on NPCBOTS. I just compiled a pure azerothcore version, and it seems that the resource usage is not high. The last 500 diffs summary value is also basically normal. But I am the only one testing online.

Confirmed. The increase in CPU usage of the Worldserver process this time is caused by game_event. eventEntry=72 (Fireworks Spectacular). The CPU usage and lag caused by this event will not automatically converge and release with the expiration of the event, and must be restarted to recover.
