Hi Could you please provide some more details about your setup and also what in detail slow and fast translates to in maybe frames per second? Answeres to the following questions might help me and others on the list help you. What are the hardware specs running your VMs Are the vms running on the same hardware or are they using different hardware (cpus) If different how is the network (switches / bridges) layout and what bandwidth are you getting 1gigabit. 10gigabit network? How many dcpomatic threads are you running on your 2 core cpus? Could you provide some log data from the dcpomatic instances running on the servers and the master? Waht is the system load on the master like during the whole process? And bottleneck an thelat side? Have a nice day Markus
