Buffer pool settings in WildFly 8.2

When I check buffer pool using CLI, it shows following result:

/core-service=platform-mbean/type=buffer-pool/name=direct/:read-resource(include-runtime=true)

{ "outcome" => "success", "result" => { "count" => 46L, "memory-used" => 10473408L, "name" => "direct", "object-name" => "java.nio:type=BufferPool,name=direct", "total-capacity" => 10473407L } }

Does this mean to increase the value? Is there any impact of this settings on performance?

this is runtime mbean statistics of jvm internal buffer pools.

if you are talking about buffer pools wildfly uses in undertow subsystem, than look into IO subsystem /subsystem=io/buffer-pool=*

Thanks!
Yes, I want to check undertow buffer pool. I see buffer cache in undertow subsystem and buffer pool in io subsystem. What is the use of both and how can we set them for better results?
