Hi Jana,

   1. Are there any performance benchmarks that have been carried out
      on databases like MySQL ?

In the early days of C-JDBC (http://c-jdbc.objectweb.org/, Sequoia is the continuation of C-JDBC) I published some TPC-W benchmark results (see http://c-jdbc.objectweb.org/current/doc/C-JDBC_Flexible_Database_Clustering_Middleware.pdf)
I don't think any new results have been published since then.

   1. Are there any production environments under which "Sequoia" has
      been already put into User ?

If the question is whether Sequoia has been used in production, the answer is yes. If you are looking for names, I cannot disclose the names of people I have been consulting for and usually few people are willing to communicate that on the mailing list once they have their system up and running (they might not read the mailing list at all after it's operational!).

   1. Is Continuent's current commercial offering bases its platform
      on Sequoia?

Yes. uni/cluster is basically a full Sequoia with a proprietary group communication and few proprietary add-ons for database specific backups, SQL dialect issues and I think more recently an administration console.

Hope this helps,
Emmanuel
