Added it to the Mac mini that we had been using. We are experiencing much slower send and receive, reserve all, and release all (especially), in 21 compared to 19. Is anyone else experiencing this? Any thoughts?</T></DIV> Wed, 23 Aug 2017 21:04:41 GMT https://community.graphisoft.com/t5/Teamwork-BIMcloud/AC21-BIM-Server-very-slow/m-p/223497#M1075 Anonymous 2017-08-23T21:04:41Z https://community.graphisoft.com/t5/Teamwork-BIMcloud/AC21-BIM-Server-very-slow/m-p/223498#M1076 That’s a tricky question, there are many factors that can affect the performance of a BIM Server.
