5.5 mm in 1.25 nanoseconds

Randon ASCII

That meant I started having regular meetings with the hardware engineers who were working with IBM on the CPU which gave me even more expertise on this CPU, which was critical in helping me discover a design flaw in one of its instructions , and in helping game developers master this finicky beast. To the left of that is one of the CPU cores.

USENIX SREcon APAC 2022: Computing Performance: What's on the Horizon

Brendan Gregg

My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory. Ford, et al., “TCP

Optimizing Performance With Resource Hints

Smashing Magazine

The browser caches the results of these lookups, but they can be slow. This enables the browser to get ahead of the game and do more work in parallel, decreasing the overall load time. You might think of a prefetch as being a bit like adding a file to the browser’s cache. When Should I Use dns-prefetch ? The as Attribute.

Scaling Amazon ElastiCache for Redis with Online Cluster Resizing

All Things Distributed

Redis's microsecond latency has made it a de facto choice for caching. Four years ago, as part of our AWS fast data journey, we introduced Amazon ElastiCache for Redis , a fully managed, in-memory data store that operates at microsecond latency. Whether it is gaming, adtech, travel, or retail—speed wins, it's simple.

Supercomputing Predictions: Custom CPUs, CXL3.0, and Petalith Architectures

Adrian Cockcroft

In recent years GPU development that was originally funded by the gaming market (and ended up being used as a supercomputer accelerator) has been dominated by use in the AI/ML accelerator market. Many HPC workloads synchronize work on a barrier, and work much better if there’s a consistently narrow latency distribution without a long tail.

Embrace event-driven computing: Amazon expands DynamoDB with streams, cross-region replication, and database triggers

All Things Distributed

Streams provide you with the underlying infrastructure to create new applications, such as continuously updated free-text search indexes, caches, or other creative extensions requiring up-to-date table changes. Cross-region replication allows us to distribute data across the world for redundancy and speed. ” DynamoDB Triggers.
