[chef] Re: chef-server 11.0.12 tuning guide?

I bumped those up and things have improved.

Could someone explain:

erchef['max_cache_size']	Default value: 10000.

Is this max number of objects?  Total bytes cached?  Max size of any single object in the cache?

I’ve found very little on tuning chef-server.  There is
erchef['ibrowse_max_sessions’] but that would be for outbound
connections, i.e  erchef->solr.  Is there a parameter for the number
of incoming connections to erchef?

One part of the config that limits the number of concurrent connections
an erchef server is able to handle is the db connection pool
size. Without seeing more details on logs and such, my first guess is
that the erchef server is exhausting its db connection pool.

You can tune the db connection pool and the max connections allowed by
postgres.

   erchef['db_pool_size'] = 100
   postgresql['max_connections'] = 200
