Main theme
- Reuse resource
- Optimize code efficiency
- Caching to avoid IO
4 performance metrics need to be collected, unfortunately only the 1st metric was presented at video
Serial Latency
Network Latecny
Pooling the connection / using persisted connection to avoid overhead recreating the connection
Compression of the payload / Data
Parallel Request Latency
Optimize one instance of each tier first before moving to scalability, all hardware, bandwith, storage, network, CPU, threadpool can be taken into account for optimization
