[jira] [Created] (TINKERPOP-2445) Speed up client initialization

Divij Vaidya created TINKERPOP-2445:
---------------------------------------

             Summary: Speed up client initialization
                 Key: TINKERPOP-2445
                 URL: https://issues.apache.org/jira/browse/TINKERPOP-2445
             Project: TinkerPop
          Issue Type: Improvement
          Components: driver
    Affects Versions: 3.4.8, 3.5.0
            Reporter: Divij Vaidya


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.

As part of this task, we should profile the start-up time and identify other places where we could optimize the start-up time.
