1 memory compression technology introduced In order to save storage space or transmit bandwidth, data compression technology has been widely used in computer systems. When a magnetic medium stores data or a network transmits data, people use a variety of compression techniques based on hardware or ...

cmix is a lossless data compression program aimed at optimizing compression ratio at the cost of high CPU/memory usage. - byronknoll/cmix
我们讨论了数据压缩(compression)和数据压实(compaction)[1]这两个互补的主题,提供了有关的高级概念(high-level concet)[12],并说明它们在曾经提出过的设计中是如何具体体现的。 然后,我们引入了一个分类法(taxonomy),以帮助理解对于不同级别的存储结构层次,哪些压缩算法最适用。
Crypto and compression. Was in PCH before. Integrated to CPU and will be called QAT 4.0 on 4th Gen Intel® Xeon® Scalable processors. ECRC (End-to-End CRC) ECRC is carried forward by PCIe switch. Only checked when reach final destination PCIe End Point. ...
It uses only ballooning and hypervisor-level swapping to reclaim memory. ESX, on the other hand, works for all guest OSes. It also uses content-based page sharing and memory compression. This approach improves VM performance as compared to the use of only ballooning and hypervisor-level ...
CPU is 33%. The memory consumption and release (through GC) is stable. The CPU (33%) is not over-utilized, therefore the garbage collection can keep up with a high number of allocations. Workstation GC vs. Server GC The .NET Garbage Collector has two different modes: Workstation GC: ...
考虑到我们新的数据页编码结构中,每次读取会将多个需要先后比较的index key同时load进CPU cache, 引入SIMD指令集可以实现在一个CPU cycle内并行检索完在cache中的多个index key。 为了使用SIMD指令集,我们需要对X-Engine的数据页编码继续进行调整,如下图所示: 对key进行lossy compression:由于SIMD寄存器的处理单位...
