Thousands of bars don't fit on the screen (only 30 or so), so it's a GUI problem if aMule does draw all of them all of the time even if they are invisible
.
Or even minimised. No point doing any drawing at all then.
One important point: Stu's non-compressed EC mod dropped cpu usage AND sped up synchronisation by 90%++ (seconds vs minutes)
I've made the request before to disable EC compression on non-WAN connections or make it switchable, but that mod underscores that EC compression is counterproductive on fast links (localhost/LAN connections)
(Yes, I know I'm abusing the program by driving this hard. Call it "stress testing" )
