For example, memory-resident databases without persistent disks, such as Redis cluster setups or Apache Spark installations, rely on stand-alone machines. To traditional relational databases, where rollbacks are less likely to cause data loss, MongoDB differs significantly.

Performance issues surrounding Availability Groups typically were related to disk I/O or network speeds. Our customers who deployed Availability Groups were now using servers for primary and secondary replicas with 12+ core sockets and flash storage SSD arrays providing microsecond to low millisecond latencies. one without a replica).

Some of the built-in features ( wal_compression ) have been there since 2016, and almost all backup tools do the WAL compression before taking it to the backup repository. Such “torn pages” are corruptions from the database point of view. Individual processes generate WAL records, and latency is very crucial for transactions.

Back in 2016, I gave a talk outlining the causes and effects of the terrible performance of web apps built using popular tools on the fastest-growing device segment: low-end to mid-range Android phones. In 2016, Jio swept over the subcontinent like a monsoon dropping a torrent of 4G infrastructure and free data rather than rain.

This processor has a base clock speed of 2.0GHz, with an all-core boost speed of 2.55GHz, and a max boost clock speed of 3.0GHz. Both of these Intel processors are special bespoke models that are not in the Intel ARK database. They feature low latency, local NVMe storage that can directly leverage the 128 PCIe 3.0

This is a complex topic, but to borrow from a recent post , web performance expands access to information and services by reducing latency and variance across interactions in a session, with a particular focus on the tail of the distribution (P75+). Consistent performance matters just as much as low average latency.
