Hello, First thanks for your great product I've been using for years. Recently, I worked on a project that uses JDBCStore to store sessions. I had to run performance tests on it. Those tests revealed a high contention point in this component due to the coarse granularity of synchronization. The impact was that 1 thread could block hundreds of others leading to high response time at higher scale. So I implemented (based on existing one) a new one with following differences: - I kept only the dataSourceName based configuration - I removed stateful instance variables in order to be able to lift synchronization This new implementation improved drastically performances. I am aware that there is duplication with JDBCStore that could be improved but it's a first shot and I lack of time unfortunately. I hope you can take into account this contribution.
