Updating existing products results in nearly the same picture as the “create products” benchmark. Interestingly, the impure service performs about 20% better on an update than on a create.

The other metrics are nearly identical to the first benchmark. The pure service uses a bit more memory (around 8%) but is around 6 times faster than the impure one, causing only half of the system load.
