Many network and server-related factors contribute to a high TTFB score in ecommerce. If your hosting or platform provider has under-resourced their servers and infrastructure, it can lead to slow response times, especially when experiencing peak traffic. If the hosting servers are physically far from your customers (for example, someone in New York accessing a server in California), response times can be slowed down as requests travel across the network. Back-end issues such as excessive server-side scripting and database queries can also impact your TTFB. Many other factors, such as plugins and resource-heavy content management systems can also contribute to slow TTFB.
