In a constantly changing environment, brands are likely to be iterating on sites and applications to make them bigger, faster, fancier, and more engaging while pushing the new and updated code out as quickly as possible. Without a set plan in place, any new script can damage performance, affecting user. The post Debunking 5 Myths About Performance Budgets appeared first on Production.

I explained that SQL doesn't provide you with the ability to distinguish between missing and applicable (A-values) and missing and inapplicable (I-values) markers. I also explained how comparisons involving NULLs work with constants, variables, parameters and columns.

When it comes to connection pooling in the PostgreSQL world, PgBouncer is probably the most popular option. It’s a very simple utility that does exactly one thing – it sits between the database and the clients and speaks the PostgreSQL protocol, emulating a PostgreSQL server.

One of the key tools that performance engineers have at their disposal is the Performance Budget: it helps us—or, more importantly, our clients—ensure that any performance-focused work is monitored and maintained after we’ve gone. By establishing an acceptable threshold, be that based on RUM data, bundle analysis, image weight, milestone timings, or any other suitable metric, we can be sure that new or unrelated bodies of work do not have a detrimental impact on the performance of our site.
