Performance issues

[dnbghnksrghb]

Place blocks or right click items caused proxy lag and using huge of CPU and no error

To reproduce just need about 15 ~ 30 cps to right click / place block

Proxy: Velocity/Flamecord (both lastest) , only install protocolize(1060) and protocolize-legacy(949)

Server: Paper 1.8.8
Client: 1.8.9

Same issue we meet. Players quickly take out or put in items from / to chest can cause a lag, client will see a high ping at that time.

After uninstall protocolize, the bug disappeared. Then I found this issue post, the same cpu usage found out too.

Using BungeeCord latest build with protocolize 2.3.3:1069.

Hello, sorry, with some version this stopped happening or to this day you still have this problem.
The same thing really happens to me.

Hello, I have identified the cause of this problem, the problem is caused by the use of stream in this code line

protocolize/protocolize-api/src/main/java/dev/simplix/protocolize/api/SimpleMappingProvider.java

Line 31 in f1fa885

return (T) mappingMultimap.get(mappable).parallelStream()

the solution is to make a rollback as it was in the following commit 9618235

Should be fixed in the latest protocolize build
