Hi SIlver Surfer,
I have a few ideas, but for the most part you sound like your set up fine, however, the Peerguardian does concern me, they aren't what they used to be and are part of the reason that the patch your using (if you have winmxgroup 3.0 as i suspect) has a built in block list maintained for WinMX specifically. While your using WinMX I would leave PG2 off, frankly I would always leave it off but .. thats me.
Recently we found that the Bluetack folks that make the blocklists PG2 uses were adding IPs as we added them to our list, thats all fine and dandy until you realize a few things.
1. The riaa hired companies doing the flooding are routing through normal ISPs on Dynamic IPs. Meaning when they change those IPs they are placed back into a residential customer pool. If these are not maintained closely and removed when not in use by the RIAA companies anymore your blocking more and more potential users from yourself.
2. When we complained about this.. nicely I might add, they responded by places ALL the peer caches everyone uses to connect on the block lists. When we complained about that they blocked our personal and site IPs also.. really great folks over there.. lol
Apparently your not allowed to complain, or make suggestions so now we are all on the list, and at times you may find it impossible to connect while using peer guardian or even impossible to get to this site or the WinMX Group sites.
We for the above reasons dont feel Bluetack can be responsible or trusted and until PG2 make and host their own lists dont recommend it.
About the Throttle Process Interval, this is best left to defaults and is rarely recommend to be changed. As far as I am concerned for the most part unless you find WinMX using too much bandwidth for uploads when your hosting or something going on like that, I would not change anything here.. leave it all set to Unlimited. If your concerned about bandwidth limits then see this page for tests and recommendations
https://www.winmxworld.com/scripts/bandwidth/ << best run with MX off.
Queues are not what they used to be, you have to consider that the network did loose lots of users when the FrontCode Caches were taken offline, however on that same note (and I always think of that Kevin Cosner line from Postman when i say this)
Things are getting better. We see new users daily in the help rooms not to mention the new users coming here.. so I dont think its a settings problem just something that needs more time.
The main settings that you may want to take a look at that will have a true effect on your P= and S= numbers are those located in Settings > WinMX Peer Network > Allocated bandwidth. Here is where you can set how many P= you will have KB/s OUT and how many S= you will get with KB/s IN, a good balanced settings is around 9-10 KB/s Out.
Hope this helps with some things and if not ask away..
