[infinispan-dev] Optimising default cache access in Hot Rod

[galder at redhat.com]

Hi guys,

This came to my mind while sleeping. While I was profiling the Hot Rod server, I noticed that some time (3%) was being used reading the string cache name from the wire and transforming it to UTF-8. 

Now, in the test I was acting against the default cache which we had established to be requests sent to "___defaultcache" would be considered to be directed to the default cache. However, I'm thinking that this is waste of space. We could make things even quicker when default cache is used by simply assuming that if the length of the String is 0, followed by nothing, then the default cache will be used. If a length other than 0 is passed, the String follows and we have to read it.

WDYT?
