   Yes. Lookup by encoded name is expensive:
   ```
   
     public RegionState getRegionState(final String encodedRegionName) {
       // TODO: Need a map <encodedName, ...> but it is just dispatch merge...
       for (RegionStateNode node: regionsMap.values()) {
         if (node.getRegionInfo().getEncodedName().equals(encodedRegionName)) {
           return node.toRegionState();
         }
       }
       return null;
     }
   
   
   ```
   
   I took a look for the JIRA on improving lookup, but couldn't find it. Made 
HBASE-23561
