Why are timers slowing my site?

I'm experiencing frustrating performance issues with countdown timer apps on my e-commerce site. Every time I install a new timer to create urgency for my promotions, I notice significant page load slowdowns that seem to negatively impact user experience and potentially hurt my conversion rates. I need to understand why these timers are causing performance problems and how I can implement them without compromising site speed or customer experience. What technical factors contribute to timer-related site slowdowns, and what solutions can help me maintain both urgency and performance?
