Sometimes developers only care about speed. Some will claim that any type of RPC communication ends up being faster (meaning it has lower latency) than any equivalent invocation using asynchronous messaging. It’s less of an apples-to-oranges comparison and more like apples-to-orange-sherbet. So we’ll just use “RPC” for short.

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.

Anyway, the following patch seems to make the load average much more consistent WRT the subjective speed of the system. I generated this using my offcputime tool from [bcc] (this tool needs eBPF features from Linux 4.8+), and my [flame graph] software: #./bcc/tools/offcputime.py Latency was acceptable and no one complained.

Also, we will take a look at our open-source backup utility custom-built to help avoid costs and proprietary software – Percona Backup for MongoDB or PBM. The speed of backup also depends on allocated IOPS and type of storage since lots of read/writes would be happening during this process. Records backup progress logging.

Compared to the most recent master version of libaom (AV1 reference software), SVT-AV1 is similar in compression efficiency and at the same time achieves significantly lower encoding latency on multi-core platforms when using its inherent parallelization capabilities.

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.

The caching of data pages and grouping of log records helps remove much, if not all, of the command latency associated with a write operation. The following are a few reasons this error may be encountered. SQL Server uses read-ahead logic to avoid query stalls caused by I/O waits.

Using just a few (but still more than one), however, could nicely balance congestion growth with better performance, especially on high-speed networks. Finally, not inlining resources has an added latency cost because the file needs to be requested. In our own early tests , I found seriously diminishing returns at about 40 files.

Assuming encode/decode speeds meet your needs. Encode/Decode Speed. Degree of compression, image quality, and decoding speed are key factors to be considered when comparing image performance for the web. A tl;dr of recommendations can be found below.
