Description

I have setup Authorization in my Gremlin Server instances (v3.0.2), backended by Titan v1.0.0 and Cassandra.
I am testing SimpleAuthenticator, with the following snippet from my gremlin-server.yaml:

authentication: {
className: org.apache.tinkerpop.gremlin.server.auth.SimpleAuthenticator,
config: {
credentialsDb: conf/tinkergraph-empty.properties,
credentialsDbLocation: data/credentials.kryo}}
ssl:

{ enabled: false}

I am using the default serialization file of TinkerGraph credentials.kryo, with only the default user stephen/password.

I am using Basic Auth in my requests to Gremlin Server, by passing the header "Authorization" with the value "Basic c3RlcGhlbjpwYXNzd29yZA==".

Authorization works as expected. Therefore, the Gremlin Server becomes pretty slow! It takes 10x more time and consumes 5x more CPU (from 10% to 50%) to handle the same simple traversal Http POST request (below) in batch, compared to Gremlin Server with NO authorization!

{
"gremlin": "g.V().has('CONTENT','id', 'LinkPost:7330001').count()"
}

Is there a workaround to this?

Ps. If there is a fix, could it be patched for version 3.0.2? I am limited to this version because I use Titan 1.0.0.

Thanks.
