Capacity patterns

Pool connections

basic
timeout for connection checkout
monitor waiting times
undersized pool -> contention

## Use Caching Carefully

limit cache sizes (memory usage)
monitor hit rates
consider generation time before caching
when possible pre-compute instead
consider risk of stale data (TTLs, flushing) and access and change frequency

Precompute content

Precompute content that changes infrequently

Tune the Garbage Collector

tune it and revise for each release
don't pool objects
