Hi,
We are using the latest ncs release (2.0.2) on a nRF52840 integrating Matter. When looking at the sample apps (e.g. light switch example), the RAM usage for the Matter part is really high (~80% of the available RAM), which leaves little space for adding additional, Matter or non-Matter related, features.
I know there is this page that gives a few hints on what one could look at but that still leaves little room for improvement outside of what one would normally assume. (e.g. we are already doing release builds) What is not covered for example is the topic of different buffers size increase in the examples (e.g. BLE, net_pckt_cnt) and the impact of changing that. We could of course apply trial and error on our end to see when we reach a "sweet spot", but we would still not know if this affects interoperability with other Matter devices or poses Certification issues.
Also, when looking at the configuration for an FTD (e.g. light bulb) and MTD (e.g. light switch), there seems to be no difference in the buffer sizes (e.g. NET_BUF_RX_COUNT is 80 for both) but I guess FTD and MTD are expected to handle different scenarios. Should we look into tweaking those or are those fixed to the defined values (since there is no difference to them in the above mentioned page)
Did anyone else face the same issues and has any ideas on where/what to tweak?
Thanks,
Sebastian
