Yesterday we completely finished with our performance optimization Stage 2 (advanced techniques). Let’s review how much acceleration we have got during this process. Actual progress As you can remember we have website load time about 4.2 seconds (clean cache) and the following YSlow chart. N...
We reviewed multiple hosts application to our website and get a little more speedup. So let’s see how CDN (Content Delivery Network) can help us. Actually CDN is a large number of servers which are distributed all over the world and have very good connection timings (so every HTTP request cos...
