> SimpleAuthenticator over HttpChannelizer makes Gremlin Server pretty slow and

> Key: TINKERPOP-1189
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1189
> Project: TinkerPop
> Issue Type: Improvement
> Components: server
> Affects Versions: 3.0.2-incubating
> Environment: Gremlin Server 3.0.2 backended by Titan 1.0.0 and
> Cassandra (separate instance), running in a server with 2 CPUs / 7.5 GB RAM
> (Linux Debian 3.16.7)
> Reporter: Gabriel Moreira
> Assignee: stephen mallette
> Priority: Minor
>
> 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.
