Performance Tuning
Here are some settings for performance tuning your servers
Max Requests
This setting limits how many requests will be passed through the Undertow listener to your app server. It defaults to 30. Please note that your web server connector and Adobe ColdFusion may also have their own max request setting.
Or as a global setting for all servers:
Max Requests can NOT be set on a per-site basis since this setting controls the size of Undertow's worker task pool. You can, however, use the request-limit( 10 )
handler in a server rule that applies only to a specific site. Keep in mind, the maxRequests setting will still enforce an overall total running threads for all sites on a server.
