Should Plex clients have more cache to allow for peak bitrates on limited bandwith?

Plex Players Streaming Devices

First time posting here.

I run a PMS on Windows, with up to 3 remote clients at any one time. My upload speed is 6Mbps.

Is there a way to increase the cache of plex clients e.g. Amazon Fire Stick or on Samsung smart TVs, so that if a remote client Direct Plays a film at an average 1.5Mbps bitrate, if the max bitrate peaked above 6Mbps, then the extra cache on the client end will stop any buffering?

I feel the extra cache on remote clients would really benefit PMS with low bandwith who have multiple remote clients.

Thoughts and advice would be much appreaciated, thanks!

many devices are limited by their hardware and/or os.

it’s hard to cache much and have room for the actual app when devices barely have 1gig ram for the whole stack.

for example, the fire stick 4k only has 1.5 gig of ram.

older fire sticks have even less.

most smart tvs are similarly extremely limited (read cheap).

also, plex does video analysis to help determine what bitrates a video contains (it only displays the average, but tracks the entire file).

It uses this information to help keep video streams under the specified upload bandwidth.

Id love for plex to offer more caching on clients that do support it though. Infuse will by default cache to disk. This allows for it to cache the whole movie. I love that feature and hope plex implements something similar
