a1boulevard.nl delivers its homepage in 13128ms (server response time), which is considered slow by industry standards. The total page weight is 41 KB, and we detected 292 resource requests loading assets from 241 third-party domains. A high number of third-party domains can significantly impact page load time due to additional DNS lookups and TLS handshakes required for each domain. The website uses Gzip compression for text-based assets, achieving an estimated 60.0% reduction in transfer size.
