Connection throttling

With the PassThrough transport and HTTP NIO transport, you can enable connection throttling to restrict the number of simultaneous open connections. To enable connection throttling, edit the <EI_HOME>/conf/ (for the HTTP NIO transport) or <EI_HOME>/conf/ (for the PassThrough transport), and add the following line:

max_open_connections = 2

This will restrict simultaneous open incoming connections to 2. To disable throttling, delete the max_open_connections setting or set it to -1.


Connection throttling is never exact. For example, setting this property to 2 will result in roughly two simultaneous open connections at any given time.
