text: Using our Cascade Lake system and limiting the etcd server to 16 cores, we ran a test scaling the number of clients from 100 to 180,000. We also placed the backing store in different locations, either in the pmem0 directory mounted as above, in an Optane NVMe drive, or on a traditional flash-based SSD. We also used two values for the number of connections per client—5 and 50.
