> Project: TinkerPop
> Issue Type: Improvement
> Components: groovy
> Affects Versions: 3.2.4
> Reporter: Bryn Cooke
> Assignee: stephen mallette
>
> Currently there is no synchronisation around script compilation. This means
> that if a particularly heavy script is in use, many threads may end up
> compiling the same script.
> It would seem like a good idea to have some some sort of synchronisation to
> prevent ever getting to this stage.
> In addition, there will be cases where users will repeatedly submit broken
> scripts to the server. In this case it is useful to log the error the first
> time the script compilation is attempted and then cache the error for
> subsequent runs.
> Finally I have found some scripts take in excess of 30 seconds to compile. To
> aid performance debugging the script compilation times should be included in
> the logs.
