Benchmark (YCSB) numbers for Redis, MongoDB, Couchbase2, Yugabyte and BangDB

High Scalability

We note that for MongoDB update latency is really very low (low is better) compared to other dbs, however the read latency is on the higher side. The latency table shows that 99th percentile latency for Yugabyte is quite high compared to others (lower is better). Again Yugabyte latency is quite high. Conclusion.

Comparisons of Proxies for MySQL

Percona

When deciding what to pick, there are many things to consider, like where the proxy needs to be, if it “just” needs to redirect the connections, or if more features need to be in, like caching and filtering, or if it needs to be integrated with some MySQL embedded automation.

The Performance Inequality Gap, 2021

Alex Russell

Unless a site is installed to the home screen as a PWA , any single page is just another in a series of documents that users experience as a river of links. A then-representative $200USD device had 4-8 slow (in-order, low-cache) cores, ~2GiB of RAM, and relatively slow MLC NAND flash storage. The Moto G4 , for example.

Can You Afford It?: Real-world Web Performance Budgets

Alex Russell

Budgets are scaled to a benchmark network & device. This isn’t true (more on that in a follow-up post), and sites which are built this way implicitly require more script in each document (e.g., This input processing happens on document’s main thread , where JavaScript runs. for router components).
