21 hours web series using meta human

We are producing a web series using 2 characters running into 21 hours (42 episodes). Without any experience in film making or animation, in less than 2 years, entire environment is created in Unreal. Thanx to Amit of Unreal, Mumbai office for mentoring us.
We are facing challenges on performance of our machines. We have 10 machines running Ryzen series latest processors ( all but 2 are 16 core), 64 GB RAM, Nvidia 4090 and 3070 and one NAS server.
Our observations are as follows:

  1. CPU is more than 50% and RAM is even 80-90% while GPU remains between 0 to 4% when we are baking. We seem to be missing something that we are not able to configure Unreal to optimize GPU usage
  2. Our 20GB cloth rendering, 5 min scene takes more than 6 hours to render. We created Indian style clothing. 20 GB computation taking more than 5 hours is quite under performance.
  3. Does Unreal support distributed computing? We could then use all our machines (we are a tiny cloud computing environment with 10 high end machines)

Any body who has experience, please help. We are close to releasing this web series to reverse sleeplessness and mental disorders.
