Mongo slow startup after upgrade to 4.2.5
I tried with changing following 3 WiredTiger default eviction parameters:

storage.wiredTiger.engineConfig.configString:
"eviction_dirty_target=60,
eviction_dirty_trigger=80,eviction=(threads_min=4,threads_max=4)"


Now mongo is starting immediately.
Is it safe to set eviction_dirty_target and eviction_dirty_trigger values like this? Default is : eviction_dirty_target (default 5%) and eviction_dirty_trigger (default 20%). Thanks.
