The shared memory utilisation has massively jumped in the recent update. I have not seen any unintended missed blocks but I'm pretty way down on the schedule and get about 1 every 1/1.5 days.

I was out of the loop for 2 months and in that time the blockchain went from 9 to 14Gb in size, and before, I could run the plain witness in about 16gb, or maybe it was 24, but now really you need a 32Gb file and mine shows that 29gb is used, so I may have to increase it and replay in a month or two.

I am not sure how you get it running with only 10gb, I got an extra missed block because of a greater time doing replay than I expected. But when you see 9gb up to 14gb in 2 months, and based on what I saw then...

I have now experienced the joy of a computer with NVMe, and in 2 and a bit monnths time, I am going to deploy a witness on my own hardware on a business grade 100mbit connection. The good connection is the main thing people would stumble up against as to running their witness at home. The standart of internet here is so high, I even just saw that one of the big ISPs here has just announced they are rolling out 100Gbit GIGABIT! connections.
