The strictness of our memory requirements wasn’t made apparent until years later. For background, the application is a system daemon running on end-user servers. So every byte we allocate, every cycle of CPU we use, is a byte or cycle taken away from our customers. We don’t provide firm guarantees or formal SLAs on our memory usage, but we do try to minimize it whenever possible. Because what we don’t want is for someone to upgrade agent versions and suddenly our daemon is using significantly more memory and causing OOMs, or using more CPU and force customers to scale out their fleet. Our p99 cpu and memory usage right now are more or less the same as they were two years ago (RSS is under 40MB last I checked)

So it’s not like we’re running on a machine with only kilobytes of RAM, but we do want to minimize our usage.
