While in general the WebSuite2 system is very responsive, we are aware there are times when it can be slow to respond. This has to do with how the database pre-loads in data before selecting and sorting it. (The first request is slow because it is loading in the data. Subsequent requests are fast, because the data is already loaded and available.)
We are working closely with the database experts at Amazon to fine-tune all of the settings and we have a multi-step process to determine to the best configuration. We expect to have this issue resolved by the end of this week. But we appreciate your patience in the meantime.
