Subject Cassandra slow on PasswordAuthenticator
Date Fri, 02 May 2014 13:57:50 GMT
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)
