How we saved the Black Friday sales for a major jewelry shop
summary
A jewelry ecommerce site is down the night before Black Friday; an APM agent gets installed and shows garbage-collection suspensions above 60% so Dynatrace pinpoints the hotspot. Flipping to server GC=true drops suspensions to ~8% in 30 minutes, and reducing product-list queries to 16–24 items per page cuts page loads from seconds to 400–800 ms. Site stays stable for the sale and recovered within an hour.
