While we understand it’s virtually impossible to achieve a linear increase in throughput as the number of vCPUs grow, a near-linear increase is attainable. GS2 is a stateless service that receives traffic through a flavor of round-robin load balancer, so all nodes should receive nearly equal amounts of traffic.

Where a high availability design once worked well, it can no longer keep up with more complex requirements. HA in PostgreSQL databases delivers virtually continuous availability, fault tolerance, and disaster recovery. Without enough infrastructure (physical or virtualized servers, networking, etc.),

HammerDB has always used stored procedures as a design decision because the original benchmark was implemented as close as possible to the example workload in the TPC-C specification that uses stored procedures. HammerDB uses stored procedures to achieve maximum throughput when benchmarking your database. On MySQL, we saw a 1.5X

It helps assess how a site, web application, or API will respond to various traffic, without adding any additional infrastructure. Executing an internal test can tell you how well your application or site handles an increase in traffic, but it will never reflect real-world conditions.

Let’s face it – the ideal load test emulates real world traffic, yet most load testing software doesn’t come close. Today we’ll be reviewing LoadView , an on-demand load-testing platform from Dotcom-Monitor that makes realistic load testing possible without an up-front investment in hardware or software infrastructure.

Essentially, you can assign a thread to a specific virtual CPU. assigning to a specific CPU) is a manageable resource, represented by the concept of “virtual CPU” as a term that includes CPU cores, hyperthreads, hardware threads, and so forth. MySQL determines, at startup, how many virtual CPUs are available.
