> The current Java client has a lot of initialization overhead. Some of the things we could do to trim the fat are:
> 1. Parallelize the connection creation inside a connection pool, i.e. make [this for loop|https://github.com/apache/tinkerpop/blob/3.4-dev/gremlin-driver/src/main/java/org/apache/tinkerpop/gremlin/driver/ConnectionPool.java] parallel. 
>  2. Do not create a bootstrap [for every connection|https://github.com/apache/tinkerpop/blob/3.4-dev/gremlin-driver/src/main/java/org/apache/tinkerpop/gremlin/driver/Connection.java#L111]. A single bootstrap could be reused.
> 3. Remove SASL Handler from the pipeline after negotiation is complete for a connection.
> 4. Do not initialize SASL Handler if not required.
> As part of this task, we should profile the start-up time and identify other places where we could optimize the start-up time.
