Windows Overall Performance detection

It's been a long time playing Windows Server, and there's not a specific understanding of Windows.

1;windows overall performance by external to internal CPU memory hard disk sometimes NIC exception may also cause some problems # I have 2 servers with IPSec (IPSec no problem), but with the use of the ping of any domain name, restart and normal, and then a period of time and not. After the replacement of the ISO image did not appear because there has been no specific answer, so there is only a reload system.

CPU View

Always feel that Windows view CPU current situation is very intuitive, now the server standard CPU is 4 core, the bottleneck is few, also encountered several times SQL Server CPU 99% listen to the DBA said once is the index of the table is hanging. There are a few times is the process caused by the problem, specific procedures where you do not know, ashamed.

For example, an IIS server CPU usage is too high to see if the W3wp high CPU IIS process in windows2008 replaced by another name.

Memory

This ditto, intuitive

Hard disk

This is a bit of an intuitive, but the application services to disk I/O requirements are not large, the general requirement is SQL Server

I/o viewing is generally distinguished as read and write

First look at what the overall I/O load is

Avg.Disk Queue Length #等待读写 (can be called queue) the default value is 0.5 greater than this value indicates a bottleneck.

Avg. Disk Read Queue Length # The default value is 0.5 greater than this value indicates a bottleneck.

Avg. Disk Write Queue Length # default value is 0.5 greater than this value means there's a bottleneck.

2. See the performance of the program

Sometimes I don't know how many connections IIS have. There's no end to it. When a client accesses the server IIS, this time it needs to look at the number of current site connections.
