Description

Below what we have today.
I vote for 10.

configuration.xml
The default of 10 is rather low

common/hbase-site
<name>hbase.regionserver.handler.count</name>
<value>30</value>

server/hbase-site
<value>5</value>
<description>Count of RPC Server instances spun up on RegionServers
Same property is used by the HMaster for count of master handlers.
Default is 10. <===

HMaster.java
int numHandlers = conf.getInt("hbase.master.handler.count",
conf.getInt("hbase.regionserver.handler.count", 25));

HRegionServer.java
hbase.regionserver.handler.count: conf.getInt("hbase.regionserver.handler.count", 10),
