Would be interested in peoples thoughts on what realistic read/write pressure is a good level to test at, to feel confident in real-world performance... [ if not HN level dos'ing ]

Did a basic test of our new new thing, seemed to hum along okay at 10 w/sec and ~50 reads/sec - short writeup here : https://quantblog.wordpress.com/2022/06/26/mon-pho-aka-how-f...

I’m not sure whether I’m understanding those numbers correctly, but servers are expected to deal with many more zeroes than that. 10 writes/seconds reads like a meme.

Ten writes per second is abysmal, considering that even consumer NVMe SSDs have several hundreds of thousands of random write IOPS.

At the end of the day though, what matters is whether or not your application scales appropriately for your expected workload.

If your expected workload is ten writes per second, then trying to get every single bit of performance out of the hardware is probably not time well spent. If you're having to handle thousands of writes per second and you're getting ten writes per second per server, then it's probably worthwhile to look into what's causing that number to be so low.

As a followup .. I pushed writes to around 120/sec before I start to notice impact on performance [ latencies start to go up beyond that ]
