Most Intel microprocessors support “HyperThreading” (Intel’s trademark for their implementation of “simultaneous multithreading”) — which allows the hardware to support (typically) two “Logical Processors” for each physical core. leaving half of the Logical Processors idle).

It enables the user to measure database performance and make comparative judgements about database hardware and software. These factors meant that often when looking for database performance information, the results for a particular combination of software and hardware were not available. What is HammerDB? Why HammerDB was developed.

As is also the case this limitation is at the database level (especially the storage engine) rather than the hardware level. Finally it is also important to note that this comparison is focused around OLTP based workloads, HammerDB also supports a TPC-H based workload for analytics with complex ad-hoc queries.

It brought a whole range of additional features such as spatial scalability, region of interest coding, range of supported bit-depths, flexible number of color planes, lossless coding, etc. There is a potential benefit in reusing the hardware in place for video compression/decompression.

Highly Scalable

SEPTEMBER 18, 2012

Scalability is one of the main drivers of the NoSQL movement. A database should accommodate itself to different data distributions, cluster topologies and hardware configurations. Read/Write scalability. In comparison with pure anti-entropy, this greatly improves consistency with a relatively small performance penalty.

It will also use less power than a two-socket Intel server, with a lower hardware cost, and potentially lower licensing costs (for things like VMware). For comparison's sake, Lenovo has an earlier submission of an official TPC-E result for a two-socket, Lenovo ThinkSystem SR650 2U server that has a TPC-E Throughput score of 7012.53.

The solution to this challenge is to use scalable, memory-based data storage for fast-changing data so that web sites can keep up with exploding workloads. In addition, repeatedly accessing back-end databases to serve up popular items, such as product descriptions and news stories, also adds to the bottleneck.
