> I was speaking to [~belaban] on performance tuning recommendations for the upcoming EAP 7.1 Performance Tuning Guide.
> He mentioned that he could see no reason why the default JGroups TCP stack should be using FD instead of FD_ALL for failure detection. (the UDP stack already has FD_ALL as the default).
> Rather than instruct customers to change the protocol manually, it would be better if the default TCP stack could be changed to use FD_ALL by default. 
> Here are the default stacks taken from `standalone-ha.xml` in 7.1.0.DR14:

>     <stack name="udp">
