How long does it take to get the data off disk and into memory after coming online? A decade ago filling just 64GB of memory with our hot dataset was a painful process. I can't imagine it's any nicer with 768GB.
- 1996 6y agoOn a modern raid of NVME, you can do several gigs per second - with 20 PCIe Gen3 lanes on a 3400G about 10 GB/s is reasonable, for a theoretical max of 20GB/s. Assuming your system is very badly configured and you can only do 3 gigs per second, about 400 s, so about 5 minutes, which is not very painful
