This allows teams to sidestep much of the cost and time associated with managing hardware, platforms, and operating systems on-premises, while also gaining the flexibility to scale rapidly and efficiently. Every time the trigger executes, the function runs on an available resource. This creates latency when they need to restart.

A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. Was there some other program consuming CPU, like a misbehaving Ubuntu service that wasn't in CentOS? As a Xen guest, this profile was gathered using perf(1) and the kernel's software cpu-clock soft interrupts, not the hardware NMI.

Each of the two vector units can issue one FMA instruction per cycle, assuming that there are enough independent accumulators to tolerate the 6-cycle dependent-operation latency. This is an uninspiring fraction of peak performance that would normally suggest significant inefficiencies in either the hardware or software.
