Magento Open Source and Adobe Commerce
Magento 2 comes in two editions: Magento Open Source, which is free to use, and Adobe Commerce, Adobe’s licensed edition with extra business-to-business and marketing features and optional cloud hosting. We work on both. The code, themes and extensions are largely the same, so most of what follows applies to either.
Why Magento stores slow down
Magento does a lot of work on every category and search page, so its speed depends on its setup: full-page caching, a search service such as OpenSearch, a tuned database and enough server resources. Many slow stores have one of those missing or misconfigured, or an extension that adds heavy database queries. We measure first, then fix the causes.
Staying current
Adobe releases security patches for Magento 2 regularly, and stores that fall behind become easy targets. Upgrades are done on a staging copy with your extensions and custom code tested, so the live store keeps taking orders.
