Speeding up web page loads with Shandian

摘要: Web page loads are slow due to intrinsic inefficiencies in the load process. Our study shows that attributable not only contents and structure of pages (e.g., three-fourths CSS resources used during initial load) but also way loaded 15% times spent waiting for parsing-blocking be loaded). To address these inefficiencies, this paper presents Shandian (which means lightening Chinese) restructures process speed up loads. exercises control over what portions gets communicated order so is optimized. Unlike previous techniques, works on demand without requiring a training period, compatible with existing latency-reducing techniques caching CDNs), supports security features enforce same-origin policies, does impose additional privacy risks. evaluations show reduces by more than half both mobile phones desktops while incurring modest overheads data usage.
