Cassandra slow on PasswordAuthenticator
We are using PasswordAuthenticator for security and it seems reads are much slower than with the AllowAllAuthenticator. Is there anything we are missing?
The "get" is called several times in the same running jvm.
We have the permissions_validity_in_ms: 2000 (default)
Cassandra version: 1.2.5. Client: Kundera 2.9.x
A sample of calling it 100 times shows about 2 secs slower with auth than w'out.
No of Attempts(Same JVM)
Environment
No Authentication(Secs)
With Authentication(Secs)

To expand slightly, it's relatively likely that no one has done performance
optimization of auth related code.
2 seconds seems "too long" for auth, I would probably file a JIRA were I
you.

Bhaskarjya,
The latency you're seeing is likely just the cost of using authentication.
