Separate resource usage profiles #8437

   There has been talk before (and I’m surprised to not find an existing issue about it) of having different memory usage profiles. This could encompass defaults for:

   • -dbcache
   • -par
   • -maxsigcachesize
   • -maxmempool
   • -maxorphantx
   • -maxconnections
   • -maxreceivebuffer
   • -maxsendbuffer

   For desktop systems, autodetecting could be used to determine optimal settings. For servers, it could be specified on the command line. I have heard about interest in a means for specifying “Just use all the memory I have”.

   I’m not sure it even needs to encompass more than -dbcache/-maxsigcachsize (which should probably be linked themselves).

   @TheBlueMatt For the higher values, I agree. If you have 8 GB or 32 GB of RAM, you won’t modify your -maxsendbuffer necessarily. But for very low numbers, it may make sense to reduce the number of connections and buffers size to compared to the current defaults.

   • -maxuploadtarget

   I agree this would be useful (especially for GUI/desktop) users. There could also be a time-scheduler to flexible change profiles based on timeslots (use more bandwidth during nighttime, etc.).
