Slow Webhook response performance + High CPU

[RicardoE105]

Welcome to the community.

Yeah, because by default a new process is created with each request. You can change this behavior by adding the env variable export EXECUTIONS_PROCESS=main.

WorkflowRunner use 'fork' to create subprocess , when WebHook always receive request, will make many subprocess , and CPU usage so high

@shuimugan did just commit something which allows executing workflows in the main process. It can be activated like that: export EXECUTIONS_PROCESS=main It did not get released yet but you can already check out the code and test it like that. I hope it solves your problem. The memory consumption is that way now obviously much lower and workflows start immediately. Comes however with the mentioned trade-offs like just using a single CPU, workflows/main-process can block each other, …
