Mo RAM, Mo Problems (2025)
This technical deep-dive reveals a critical but overlooked performance paradox: adding more RAM to legacy systems can severely degrade performance when it exceeds CPU cache limits, resulting in up to 25% slowdowns. For IT leaders managing aging infrastructure or hybrid environments, this illustrates how hardware specifications don't always reflect real-world caching behavior, requiring rigorous performance validation before capacity upgrades. Organizations must challenge vendor claims and conduct thorough benchmarking across their system fleet, as counterintuitive hardware configurations could be silently undermining application performance.
