Re: [jetty-users] Embedded Jetty 9 handle one request at a time [expect to handle more]
|
Browsers have a simultaneous connection limit for each destination.
Older browsers had 2, more modern ones have 6 or more. Eg your code
executes on my system (firefox 34.0) in batches of 6 (ie 6
simultaneous connections).
