Performance
Getting ideal performance out of any application is a challenging and subtle area of study which is not well-understood by many developers. The biggest challenge is in dividing the problem space and understanding what actually represents ideal. When we say performance do we mean raw speed? Latency? Concurrency? Throughput? But although performance issues can come in many shapes and sizes, almost all of them have the same symptom: your users complain that your site is slow.
Developers building apps on Heroku have the same performance challenges that you would anywhere else. The good news is that we’ve created some tools and some safeguards that help identify performance bottlenecks, and then provide clear paths for ways that you can improve the situation if you so choose.
