Today I had a strange problem where the server was very slow to access the website. Although I don't know why , or record some of your own solutions!
First of all, the server, Windows 20018 R2 64-bit 8-core 24G memory, is configured as follows:
Since the server is connected to a database server on a remote intranet, it may be due to network speed? Trace it with Tracert and find that it is also normal, as shown below:
(Of course, the uplink and downlink between the two servers were also tested, so I won't go into details.)
The network speed is normal, and the CPU and memory are not too loaded, which is normal!
Write a .net program to try???
Operational tests
IO test
The test results show that the server in the middle is the server with the problem, and the other two are used for comparison, and it is still unclear what caused the specific server
The difference between the operation is 2 times, and the difference between io is 3 times, the slightest difference is thousands of miles, because the website has a lot of operations to perform, and the gap is still quite large!
The test code is as follows:
