Leverage browser caching for the following cacheable resources:…3BDK3CG%26aftb%3D1:103 (expiration not specified)…53769875%26ctb%3D1:104 (expiration not specified)…3BDK3CG%26aftb%3D1:156 (expiration not specified)…3BDK3CG%26aftb%3D1:153 (expiration not specified)…3BDK3CG%26aftb%3D1:149 (expiration not specified)…3BDK3CG%26aftb%3D1:146 (expiration not specified)…BDK3CG%26aftb%3D1:1743 (expiration not specified)…3BDK3CG%26aftb%3D1:139 (expiration not specified)…3BDK3CG%26aftb%3D1:115 (expiration not specified)…3BDK3CG%26aftb%3D1:123 (expiration not specified)…3BDK3CG%26aftb%3D1:131 (expiration not specified)…BDK3CG%26aftb%3D1:1552 (expiration not specified)…BDK3CG%26aftb%3D1:1749 (expiration not specified)…3BDK3CG%26aftb%3D1:519 (expiration not specified)…BDK3CG%26aftb%3D1:1306 (expiration not specified)…3BDK3CG%26aftb%3D1:108 (expiration not specified)…rd%26pti%3Dmobile:1000 (expiration not specified)….js?cachebust=14889653 (60 minutes)

Compressing…260x260-20170425-1.jpg could save 8.3KiB (43% reduction).
Compressing…ke_l._CB272100436_.png could save 842B (70% reduction).
Prioritize visible content

Your page requires additional network round trips to render the above-the-fold content. For best performance, reduce the amount of HTML needed to render above-the-fold content.
The entire HTML response was not sufficient to render the above-the-fold content. This usually indicates that additional resources, loaded after HTML parsing, were required to render above-the-fold content. Prioritize visible content that is needed for rendering above-the-fold by including it directly in the HTML response.
Only about 66% of the final above-the-fold content could be rendered with the full HTML response. Mobile Resources
