-----------------------------------

             Summary: Change event loop to always stall on waiting for I/O.
                 Key: TS-4260
                 URL: https://issues.apache.org/jira/browse/TS-4260
             Project: Traffic Server
          Issue Type: Improvement
          Components: Core
            Reporter: Alan M. Carroll


Currently the event loop has two wait conditions, one a condition variable and 
the other I/O ({{epoll}} or equivalent). As far as I can tell the conditiona 
variable is useful only during start up when the I/O wait data is not yet 
available. The event loop should be changed to wait on one or the other but not 
both as this can create artificial latency when an event breaks one wait 
condition but not both.
