Generally I’ve found that the biggest causes of performance issues are network latency and missing database indexes. Slow laptops for developers test neither of those scenarios! The solution is to use network emulators that can buffer packets and simulate latency. (Or just put servers in a remote cloud region instead of the local LAN.) For databases, the trick is to give developers a slow database server with full-sized data. Don’t use empty databases (schema only) during development!
