[GitHub] [couchdb] wohali commented on issue #3047: Increase slack_db min priority (was: Upgrade from 2.3.1 to 3.1.0 - leads to 100% CPU Usage on both CentOs 7 and Mac-os)

   We're going to bump the slack_dbs/slack_views values to 512MB, but leave the ratio at 2.0. If people have evidence to suggest other appropriate defaults, let us know. The problem is that any setting here will be too aggressive for some users, and too lenient for others.
   
   A potential future smoosh 2.0 could autotune in response to remaining disk space and current foreground load. 
   
   A potential future smooth 3.0 would simply calculate the future state of the universe and then change these values to avoid any bad outcomes.
   
   Towards either improvement... "pull requests welcome."
