   - very useful property.IMHO,we can set the default value of clientPortBacklog to a bigger one(e.g `500`).
   if `clientPortBacklog` = -1,it will use the default value:[50 ](https://docs.oracle.com/javase/7/docs/api/java/net/ServerSocket.html#bind(java.net.SocketAddress)
   ) (too small if server has many incoming requests).
   - need a doc.it's better to write something like this:
   	 
   
   > In high requests-per-second environments you need an high backlog in order
   > 	 to avoid slow clients connections issues. Note that the Linux kernel
   > 	 will silently truncate it to the value of /proc/sys/net/core/somaxconn so
   > 	 make sure to raise both the value of somaxconn and tcp_max_syn_backlog
   > 	 in order to get the desired effect.if clientPortBacklog = -1,it will use the default value:50
   
   BTW, @joshelser   Sir,nice to see you in the zookeeper community.
