This is my samply cmd:
samply record --browsers --breakpad-symbol-server https://symbols.mozilla.org/ --windows-symbol-server https://msdl.microsoft.com/download/symbols MOZ_DISABLE_CONTENT_SANDBOX=1 ETW_ENABLED=1 JIT_OPTION_enableICFramePointers=true JIT_OPTION_emitInterpreterEntryTrampoline=true "C:\Program Files\Firefox Nightly\firefox.exe" --wait-for-browser

STR:
Start samply with the above cmd -> IT will open Nightly.
Open the testcase on Nightly. Let it run for 20-30s (probably 15s is enough)

AR:
The generated ETL file is 4GB+
Samply takes 2GB+ RAM after it reads/processes this large ETL file and opens the profile in the browser.
