connections, because it provides the best scalability.
Performance Test Result 1 for different Winsock I/O models is shown. The server uses the pentium4 1.7 GHz Xeon CPU and 768 m memory. The client has three PCs, which are configured with Pentium 2 233 MHz, 128 MB memory, and Pentium 2 350 MHz, 128 MB memory, itanium733 MHz, 1 GB memory. The operating systems
processor ). In this way, the CPU processing unit utilization and the corresponding data and command throughput are greatly improved.
3. Five prerequisites for hyper-threading
(1) CPU support required:
Currently, CPUs supporting hyper-Threading Technology include pentium4 3.06 GHz, 2.40c, 2.60c, 2.80c, 3.0 GHz, 3.2ghz, Prescott (pentium5) processors, and some Xeon processors.
(2) Motherboard chipset support:
The main model of the Motherboar
use x86-64 (including amd64 or intel64) architectures, including athlon64, opteron, turion64, Pentium D, Pentium extreme edition, em64t Xeon (woodcrest), and Core 2. Basically, all Intel/AMD 64-bit processors other than itanium can use this version. For non-64-bit amd computers, use PC (Intel x86 ). Of course, it is of little significance to desktop users. It is
started, the system will check the new hardware (checking new hardware) each time it is started, which will prolong the system startup time. If you do not want to add new hardware, you can close the startup service to speed up the system startup time. 27. mcstrans Description: If you use SELinux, enable it. SELinux is enabled for Fedora Core by default. 28. mdmonitor: this service is used to monitor SoftwareRAID or LVM information. The daemon related to the raid device. 29. mdmpd Description: t
processors that support EM64T technology: The traditional IA-32 mode (legacy, IA-32 mode) and the ia-32e extension mode (ia-32e mode). In a processor that supports EM64T technology, there is a widget called the extended function Activation register (extended feature enable Register,ia32_efer), where the Bit10 controls whether or not EM64T is active. Bit10 is known as the ia-32e mode active (ia-32e mode) or long pattern is valid (long model Active,lma). When Lma=0, the processor runs as a standa

Disk Array: iqstore r1500 (with two SCSI interfaces ).
Line connection: two servers are connected with a RS-232 serial line and a RJ-45 network line (1 ).

understand bus and cache Interaction
When the dataset contained in the parallel code segment causes the entire working set to exceed the L2 cache and/or the bandwidth consumed exceeds the bus capacity, be careful. On an Intel Core Duo processor, if only one thread is using L2 cache and/or bus, it is expected to obtain the best benefits of cache and bus systems, because the other core does not interact with the first thread. However, if two threads use L2 cache concurrently, if one of the follow

2via PCI-X bus structure interpretation when the industry standard ISA and VLB bus has gradually become one of the important reasons to limit system performance, due to ISA (Industry Standard Architecture) the bus can only provide 5-8 Mb/s bandwidth, so the new bus architecture of PCI (Peripheral Component In
When deploying System Center 2012 R2 Configuration Manager in an enterprise, you need to consider hardware, software, and other information to ensure that the system works properly after the deployment is complete.

confidentiality in Web service applications, thus laying a solid foundation for advanced objectives such as consortium, policy, and trust.
New-generation processors: some new technologies (such as XML signatures) used to enable Web Service Security consume more resources than some traditional technologies. The increasing demand for resources will inevitably become a stumbling block to the adoption of Web Services in the enterprise environment. However, the new generation of IA64 processors p
upload the image. The client sends a request to modify the image and uploads the new image to the Web server. The Web server accesses the database to obtain the URL address of the old image, and calls the image deletion function to delete the old image, finally, the upload image function is called to complete the upload of the new image. Finally, modify the image database to record the URL path of the new image. The algorithm flow is shown in step 5.
Iv. System Performance Analysis
In the LAN
consider configuring RAID arrays; when high requirements on memory, you should provide 1 ~ 2 GB memory.
If the server supports a multi-CPU architecture and is not filled with all the CPU sockets, you can simply increase the CPU to improve the processing performance of the server.
