Common Questions
Is upgrading to Shopify Plus actually a legitimate performance-improvement strategy, or does it only address checkout-specific scale, not general site speed?
Shopify Plus is not a site-speed upgrade, because every Shopify plan gets the same hosting: "Fast load times and unlimited bandwidth" (shopify.com/pricing, October 2026). Plus adds checkout scale for flash sales instead: high-volume checkout and bot protection (shopify.com/pricing, October 2026). Storefront speed comes from your theme, apps and added third-party code (Shopify Help Center, October 2026).
Do all Shopify stores on the same plan get identical baseline infrastructure performance, or does Plus actually run on faster infrastructure?
Shopify Plus runs on the same storefront infrastructure as every plan, because every online store gets fast global servers and a Cloudflare content delivery network (Shopify Help Center, October 2026). Plans differ in app throughput: 1,000 GraphQL Admin API (application programming interface) points a second on Plus, 200 on Advanced (Shopify developer docs, October 2026).
How do I know if my Shopify performance problem is severe enough to justify hiring an agency versus something my in-house team can fix in a day?
A Shopify performance problem needs an agency only when the fix needs profiling or code you cannot edit, like theme JavaScript. In Deploi's judgment, leftover app code, oversized hero images and dead tag-manager tags are a one-day in-house job. App code lingers because uninstalling an app "doesn't automatically remove its code from your theme" (Shopify Help Center, October 2026).
