905.701- Configurator Slow To Open in SO Entry

We have a configurator with quite a few "keep when" rules but otherwise nothing out of the ordinary, but when clicking on configuration button in SO Entry it can take up to 40 seconds for the configuration to open. These are configurations that were there prior to the 905.701 upgrade.We have run all conversions but still seeing response time issues

Anyone out there who can share similar experiences and what you found?
