Lemme find my post...
Old clients account for 39% of all blocks submitted. With the dupes,
that's 43%. The chance that any old client is doing a duplicate block is
New Clients account for 61% of all blocks submitted. With dupes it is
57%. The chance a new client is doing a dupe block is 9%.
Speed for the day 04/07 was 14,734,145,666 keys/sec. Dupes sucked
2,462,851,812 keys/sec from that. If there were 0 dupes, and all dupes
are checked we could have done 17,196,997,478 keys/sec on 04/07. This
means d.net runs at about 85% of optimum speed.
It's not 1% nor 40%. It's about 15% of all blocks turned in are dupes.
Old clients do 40% of all blocks. 22% of 40% are dupes.
New clients do 60% of all blocks. 9% of 60% are dupes.
If you can get to those stranded clients, please upgrade them. This
should not be a "Why?" type of thing, it should be a "Ok, as soon as I can
get to them" kinda thing instead.
