I don’t disagree that Salesforce is slow but this is a different workload, think db/business logic to perform a task, processing records, etc, not loading a typical page/assets.
i just signed up for a trial of salesforce and at least when there's not much data in the account it doesnt seem too slow. i was going off of what some coworkers related to me from past experience.
i think it's expected that if you're doing some editing/reporting/exporting en masse, then a couple seconds could be okay (assuming it's thousands or tens of thousands of records, not a hundred). but not for single-record actions / interactions.
hmm, i guess that explains why salesforce is universally known for being slow; 2 seconds is an eternity.
we deliver every full page on the site within 250ms from initial request to page fully loaded (with js and css fully executed and settled). images/videos finish later depending on sizes and qtys.
