Performance and Scalability

Salesforce is a multi-tenant platform — you fight for resources. Performance means staying under limits while delivering fast, scalable, predictable behavior.

Good general rules

• Always bulkify

• Minimize database trips via Selectors + UoW

• Push heavy and retry-prone workloads async

• Cache when the risk of stale data < cost of re-querying

• Preserve transaction independence — avoid cascading failure chains
