API performance issues can silently erode user experience, strain resources, and ultimately impact your bottom line. I've grappled with these challenges firsthand. Here are the critical pain points I've encountered, and the solutions that turned things around: ð—¦ð—¹ð˜‚ð—´ð—´ð—¶ð˜€ð—µ ð—¥ð—²ð˜€ð—½ð—¼ð—»ð˜€ð—² ð—§ð—¶ð—ºð—²ð˜€ ð——ð—¿ð—¶ð˜ƒð—¶ð—»ð—´ ð—¨ð˜€ð—²ð—¿ð˜€ ð—”ð˜„ð—®ð˜† ð—£ð—¿ð—¼ð—¯ð—¹ð—²ð—º: Users abandoning applications due to frustratingly slow API responses. ð—¦ð—¼ð—¹ð˜‚ð˜ð—¶ð—¼ð—»: Implementing a robust caching strategy.
