### Note
## Note
A small blurb to describe your relay instance. This will show up on the relay's home page.
note: "Make a note about your instance here."
### Post Limit
## Post Limit
The maximum number of messages to send out at once. For each incoming message, a message will be
sent out to every subscribed instance minus the instance which sent the message. This limit
is to prevent too many outgoing connections from being made, so adjust if necessary.
Note: If the `workers` option is set to anything above 0, this limit will be per worker.
push_limit: 512
### Push Workers
The relay can be configured to use threads to push messages out. For smaller relays, this isn't
necessary, but bigger ones (>100 instances) will want to set this to the number of available cpu
threads.
workers: 0
### JSON GET cache limit
JSON objects (actors, nodeinfo, etc) will get cached when fetched. This will set the max number of
objects to keep in the cache.
