Now, with viewers all over the world expecting flawless and high-definition streaming, video providers have their work cut out for them. This type of traffic originates directly from the server, making it more challenging to handle due to latency and server load considerations; it’s hard but not impossible. Those days are long gone.

A Primer on Speed. Discussing performance and “speed” can quickly get complex, because many underlying aspects contribute to a web-page loading “slowly”. Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Congestion Control.

A then-representative $200USD device had 4-8 slow (in-order, low-cache) cores, ~2GiB of RAM, and relatively slow MLC NAND flash storage.

For example, to reduce latency, serverless platforms try to reuse the same function instance to process multiple requests. Serverless functions are stateless , but can opportunistically reuse cached state across invocations to speed up start times. Don’t do that! a persistent store with transaction support).

Cons of logical backups As it reads all data, it can be slow and will require disk reads too for databases that are larger than the RAM available for the WT cache—the WT cache pressure increases, which slows down the performance. Hence, the node would still be available for other operations. Records backup progress logging.

Here's a short (and definitely not exhaustive) list of things that you may want to consider when running performance tests on an integration environment: Caches may need to be warmed up beforehand. Production environments typically have high cache hit ratios, and this should be replicated during performance testing.

These cores have 2 functional units supporting Vector Fused Multiply-Add instructions, with 5-cycle latency on Haswell/Broadwell and 4-cycle latency on Skylake processors (ref: [link] ). With 2 FMA units that have 5-cycle latency, the code must implement at least 2*5=10 independent accumulators in order to avoid stalls.

Stable media is commonly physical disk storage, but other devices and certain caching facilities qualify as well. Many high-end disk subsystems provide high-speed cache facilities to reduce the latency of read and write operations. This cache is often supported by a battery-powered backup facility.

Using just a few (but still more than one), however, could nicely balance congestion growth with better performance, especially on high-speed networks. This approach was touted to be better for fine-grained caching because each subresource could be cached individually and the full bundle didn’t need to be redownloaded if one of them changed.
