> Since: UNOMI-724 the sessions are now loaded using query.
> This ticket need to:
>  * measure performance difference with previous implem that was doing a direct load instead of query
>  * Take action in case of performance drawback
>  ** Consider in memory cache system to cache the sessionID/index affinity
>  ** Consider doing multiple get on all indices until session is found if it's more efficient than doing a query.
> Personally I do prefer a caching here if it's require and performance show a real difference.
> h2. To be done:
>  * new perfomance test simple using jmeter to create lot of sessions and measure differences on contextrequest system stability thresholds.
>  * Depeding on results: create dedicated ticket for next steps:
>  ** cache implem for affinity
>  ** or other logic to load sessions if better idea is found.
