One of the quickest wins—and one of the first things I recommend my clients do—to make websites faster can at first seem counter-intuitive: you should self-host all of your static assets, forgoing others’ CDNs/infrastructure. Users might already have the file cached. What Am I Talking About? Risk: Slowdowns and Outages. to just 3.6s.

One of the first decisions when integrating with Elasticsearch is designing the indices, their settings and mappings. To avoid the ES query for the list of indices for every indexing request, we keep the list of indices in a distributed cache. Net, Ruby, Perl etc.). Snippet of the index mapping Fig 4.

For example, on a 128GB memory host, this can allow up to 38.4GB of dirty pages. Make sure the drives are mounted with noatime and also if the drives are behind a RAID controller with appropriate battery-backed cache. The background ratio won’t kick in until 12.8GB.

This allows the app to query a list of “paths” in each HTTP request, and get specially formatted JSON (jsonGraph) that we use to cache the data and hydrate the UI. For example, the artwork service is separate from the video metadata service, but we need the data from both in the detail key.

Because microprocessors are so fast, computer architecture design has evolved towards adding various levels of caching between compute units and the main memory, in order to hide the latency of bringing the bits to the brains. This avoids thrashing caches too much for B and evens out the pressure on the L3 caches of the machine.
