> What struck me was how often the core problems were architectural Agreed - I remember at a previous job a new guy turned up and directed a rewrite of an old Perl application into a new Go version. He crowed on and on about how Go was so much faster than Perl but the underlying issue was the original architecture (old one was pinned to a single core and polled a database once a minute, the new one was dispatching requests pulled off a Kafka queue). The old one had been written when the system was handling less than a transaction a minute and the only attempts to fix it were upgrading Perl or various libraries.
