JMeter test runs indicate that a single initialization of the default font reduces the HTTP response time by more than 50% and increases the throughout by more than 2x. JMeter test runs were not exhaustive (30000 samples using a Linux controller running in a Docker container with the JMeter test from my Windows desktop), but they showed similar or better results on multiple runs. Average response time before the change was 15ms. Average response time after the change ranged from 3-8 ms. Median response time before the change was 10 ms. Median response time after the change was 2-3 ms with one 7ms outlier. Throughput before the change was less than 200 requests per second. Throughput after the change was over 450 requests per second.

See the JMeter test plan if the testing ever needs to be repeated. A second JMeter test plan may also be useful. |
