We have scrutinized the memory usage disparity between denops v5 and v6 by utilizing the ps command to record RSS throughout the following steps:

  1. Restart the denops shared server and initiate recording.
  2. Allow for approximately 10 seconds.
  3. Launch nvim and wait for approximately 10 seconds.
  4. Execute :Gin status and wait for approximately 10 seconds.
  5. Execute :Gin log and wait for approximately 10 seconds.
  6. Execute :call ddu#start({...}) and wait for approximately 10 seconds.
  7. Execute :Silicon and wait for approximately 10 seconds.
  8. Repeat steps 3 to 7 twice (resulting in three Neovim processes).
  9. Close Neovim and wait for approximately 10 seconds.
  10. Repeat step 9 twice (all Neovim processes will be terminated after that).

Note that the plugins utilized in the aforementioned steps are:

RSS

It appears that the memory usage of v6 is approximately half of v5, and the impact of the number of Neovim processes is less pronounced in v6. Although not within the scope of this measurement, it seems that denops-silicon.vim may have a memory leak.
