Second, the Server technology verification test Processor technology: SMP technology, HT Technology, EMT64, Dual Core Memory: DDR, Ddrii, dual channel, memory mirroring, memory hot standby Disk interface technology: SATA, IDE, SCSI Disk array technology: RAID 0, RAID 1, RAID

necessarily related to the number of tasks in the queue.What is the load? This controversy has its own arguments. I personally agree that a CPU load smaller than or equal to 0.5 is an ideal situation. No matter how good the performance of a CPU is and how many tasks can be processed in one second, we can think that it is irrelevant, although this is not the case. When evaluating the

performance evaluation of the server CPU subsystem, while the latter focuses on performance evaluations of IO subsystems. We used the SiSoft Sandra Pro sr2a to test each system, which is more familiar to the average reader, and can even use the shared version to test its own system directly, so there is a more intuitive concept of our test results.

independent data services, but the data resides on the same external magnetic consolidation device. Host and from the computer Data Services synchronization, host and from the machine has heartbeat monitoring, once from the machine found the host heartbeat stopped, immediately announced the takeover of the host. The take-over process has no downtime. We take into account the continuous production process of the Xinhua pharmaceutical Group final decision to adopt the second option. The shared ex

Resolving Excessive CPU Usage: 1. Separate application pool configuration for each Web site in IIS. That does not affect each other. 2, set the application pool CPU monitoring, not more than 25% (server 4CPU), refresh every minute, when the limit is closed. Which application pool is obtained according to W3WP: 1, in the task Manager to increase the display of

up a task request on more than one scheduler, the operating system must actually switch the context of the thread back and forth on the physical processor to satisfy the continuously issued request, even if there are two logical processors on the same physical processor. If the Context switches/sec for each physical processor is higher than 5000, we strongly recommend that you consider shutting down Hyper-threading on the system and testing the performance again. Applications rarely use Hyper-t

Today, the following configuration can be done: 1. Separate application pool configuration for each Web site in IIS. That does not affect each other. 2, set the application pool recovery time, the default is 1720 hours, can be modified according to the situation. Also, set the number of W3WP processes running concurrently to 1. Then set the memory to automatically recycle when memory or CPU usage is more or less In general, this can be solved. Howeve

Description: The hardware and software environments used are Windows XP SP2, SQL Server 2000 SP2 Personal Edition, General dual-core desktop, M LAN, and host A is an existing Server with databases and massive data, machine B is the new server. Both login modes are SQL server

Account: The use of software and hardware environment for the win XP SP2, SQL Server SP2 personal version, ordinary dual-core desktop, 1000M LAN, a machine for the use of the server, the above has a database and massive data, B machine for the new server, two-machine landing mode are SQL

Recently, the company server has always been cpu100% occupied, the server is configured as dual-core xeon3.0x2,2g ECC memory. The discovery is that w3wp.exe takes up a large amount of CPU for a long time. This situation should be caused by the death cycle of the website program. You can temporarily limit the w3wp proce

to select a backup device (such as a tape drive). io Slots : Try to keep more IO slots to prevent future plugging of more PCI cards. Network : Select the appropriate network card, to ensure that networks are not the bottleneck of the system. When evaluating database server performance, the most difficult thing is how to grasp the accuracy of the problem, exactly what factors to consider. Ideally, the following elements should be consider

. S: Ratio of complexity of actual banking transaction operations to standard TPC-C benchmark environmental transactions. Because of the complexity of the actual financial business transactions and TPC? There is a big difference in transactions in the C standard test, and a reasonable corresponding value must be set. Taking ordinary savings business transactions as an example, a transaction often needs to open a large number of database tables at the same time, take out the relevant data for op
