The Three Cs: Concatenate, Compress, Cache

I began writing this article in early July 2023 but began to feel a little underwhelmed by it and so left it unfinished. Caching them at the other end: How long should we cache files on a user’s device? 4,362ms of cumulative latency; 240ms of cumulative download. And do any of our previous decisions dictate our options?

We're excited about the newly launched points of presence (POPs) in 2023! With a dedicated POP, latency for visitors is reduced even further, resulting in better loading times. The year is not yet a month old, and we have already launched 4 new points of presence on two different continents , and more will follow this year!

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

For most high-end processors these values have remained in the range of 75% to 85% of the peak DRAM bandwidth of the system over the past 15-20 years — an amazing accomplishment given the increase in core count (with its associated cache coherence issues), number of DRAM channels, and ever-increasing pipelining of the DRAMs themselves.

To understand the current status, needs, and challenges in HCM, the first workshop for Heterogeneous and Composable Memory was held with HPCA’23 on Feb 26, 2023. There are three common mechanisms to access remote memory: modifying applications, modifying virtual memory, and hardware-level cache coherence support.

One example could be using an RDBMS for most of the Online transaction processing ( OLTP) data shared by country and having the products as distributed memory cache with a different technology. Let’s see the write operations with 24 and 64 threads: We get a gain of ~33% just using sharding, while for latency, we do not have a cost.
