--- Comment #10 from falgon.comp@gmail.com --- Hello, I'm here to give you an update on our recent tests, as we were able to install and test version 2.6.9. We were able to reproduce the synchronization problem with MMR-Delta mode from 2.6, so this problem is still present on the latest version. However, we tested the simple MMR mode (without accesslog base) with all the improvements/optimizations, and it does not have the replication problem We were able to run performance tests at over 1200 MOD/s without succeeding in recreating the problem. We're now migrating to the simple MMR mode to overcome this problem.
We'll keep our MMR-Delta instances in our development environments in case you need more information, or if you need us to carry out further tests. Thank's,
