Electricity used by servers doubled between 2000 and 2005 (and has continued growing ever since) from 12 billion to 23 billion kilowatt hours. Without effective caching on the client, the server will see an increase in workload, more CPU usage and ultimately increased latency for the end user.

Screenshot: tracing read latency for PID 181: # bpftrace -e 'kprobe:vfs_read /pid == 30153/ { @start[tid] = nsecs; } kretprobe:vfs_read /@start[tid]/ { @ns = hist(nsecs - @start[tid]); delete(@start[tid]); }'. Back then I could already tell if disks were seeking by interpreting iostat(1) output: seeing high disk latency but small I/O.

Consider the set of features the circa-2000 web could handle: Starting from a text-only document format in 1990, the web added features at a furious pace in the first decade, but not in a principled way. Other use-cases weren't addressable with early 2000's tech. 86 06:16 PM · Jun 21, 2020. But not every application can make the leap.

Operational Reporting is a reporting paradigm specialized in covering high-resolution, low-latency data sets, serving detailed day-to-day activities¹ and processes of a business domain. Most of the business views created on top of the Iceberg tables can tolerate a few minutes of latency. The audits check for equality (i.e.

Users appreciate high-quality visuals, but care needs to be taken to deliver those hero images, product photos and cat memes as efficiently and effectively as possible. The efficiency of a codec can be mainly measured by how much compression it can achieve. Images are the most popular resource type on the web and are often the largest.
