GitHub user pavelekshin created a discussion: Scheduler parsing_processes count

Hi, I tried find out a answer, how scheduler -> parsing_processes correlated 
with vCPU / vRAM, and is here any guide for tune it ?

In Cloud Composer 
([Google](https://cloud.google.com/composer/docs/composer-2/troubleshooting-dag-processor))
 only funded the recommendation:

**Set the initial value to the number of vCPUs used by the scheduler, minus one 
CPU. For example, if the scheduler uses 2 vCPUs, set this value to 1. Then 
adjust the scheduler resource allocation so that it works at ~70% of vCPU or 
memory capacity.**

Is any suggestion?
