Small knitting personally think the best CPU should be the Intel Xeon e7-8870. The key parameters for the Intel Xeon e7-8870 are as follows: Number of cores: 10 Number of Threads: 20 Bus frequency: 6400 L3 Cache: 30MB Production process: 32 NM Working power: 130W CPU Architecture: 64-bit Instruction set: sse4.1,4.2 Virtualization Technology: Intel VT The basic parameters of the Intel

processor executes the current instruction, which always causes an explicit bus lock to appear (2) in Pentium4, Inter Xeon, and P6 series processors, the lock operation is handled by either a cache lock or a bus lock. If memory access is cached and affects only a single cache row, the cache lock is invoked in the operation, and the actual area in the system bus and system memory is not locked. At the same time, other Pentium4, Intel

When it was released in November 1998, SQL Server 7.0 creates new records for Baan, PeopleSoft, tpc-c single node performance, and backup and recovery benchmark tests on the Windows NT server platform.

Many well-known server providers provide up to 128 Independent IP addresses for Hong Kong Station Group servers. Although there are not as many foreign servers as in the United States, however, it can basically meet the requirements of webmasters. We know that the same IP address stores too many websites, so it is easy to be implicated by other websites or be judged as a group by search engines and punished. How to select a group server on the Hong Kong site can avoid these risks. Hong Kong ser

Lspci-list all PCI devices Popularization of pci: PCI (Peripheral Component Interconnect) is a bus standard that connects the motherboard of an electronic computer and external devices. Common PCI cards include NICs, sound cards, modem, TV cards, and disk controllers, as well as USB and serial ports. The original video card is usually a PCI device, but soon its bandwidth is insufficient to support the performance of the video card. PCI graphics cards are currently only used when an additional ex

example that the 1 GHz itanium chip can behave almost as fast as the 2.66 GHz Xeon/opteron chip, or 1.5 GHz itanium 2 is about as fast as 4 GHz Xeon/opteron. The computing speed of the CPU depends on the performance indicators of the CPU pipeline. Of course, the clock speed is related to the actual computing speed. It can only be said that the clock speed is only one aspect of the CPU performance, not the

each logical core ran only 1 CPU threads, if hyper-threading is turned on, then the number of CPU threads = Number of physical CPUs * Number of logical cores per physical CPU *N, because each logical core ran 2 CPU threads. So, above the 24=2*6*2, you can judge that Hyper-threading is currently turned on. 1 2 3 [email protected] ~]# Cat/proc/cpuinfo | grep "model name" | Uniq Model Name:intel (R) Xeon (r) CPU X5670 @ 2.93GHz [ema

The recent release of the IntelXeon5500 series processor Nehalem-EP began to calm down. During this release, RedHat became the most attractive partner. Intel called the series of processors "the most revolutionary server processor since the launch of the IntelPentiumPro processor 15 years ago ". This statement proves to be among the numerous new performance records created during the release activities. During the release, RedHat and our partners are testing eight different industry standards. T

For the leveldb standard version compilation, see here. Because the standard version uses the C ++ 0x feature, it is not supported on the RHEL platform, so for portability, for Basho, see the Standard C ++ version of port here.
