Nobody is talking (again) about the lack of found blocks. The average is 9.6 minutes instead of the intended 7 minutes, that is, around 150 blocks are found per day instead of ~205.
Here are the stats for the previous 7 days:
Sep 11: 7026-7201 (175)
Sep 12: 7202-7354 (152)
Sep 13: 7355-7503 (148)
Sep 14: 7504-7654 (150)
Sep 15: 7655-7805 (150)
Sep 16: 7806-7952 (146)
Sep 17: 7953-8105 (152)
So there was a noticable increase shortly after the F7000 (although still not enough), but then it went back to the slower block time.
I speculate this issue is closely related to a lot of other issues, so when one of the other issues is fixed, this may be fixed with it, or vice versa.
I did notice it last week, but I thought this is not priority to fix, so I never raise up yet, just wanted to let Robert concentrate on fixing the other issues (because there are 2 impatient guys keep pushing dev, I think they must be paying dev a lot
BTC, lol).
@inblue you remind me

I think it is good time to discuss about this issue now, since wallet and pool are working great right now

Yes, I waited too because there were obviously more important issues then, and also to have at least 7 days to confirm the average.
