Two ways to slow down a server

Server slows down unconventional solution a scene in the Netcom computer room hosted a server, hundred M exclusive. Spent a lot of money, of course, to create higher value, the server is mainly used to do video on demand. But from the day of hosting, never feel 100M alone in the end how fast, and then after testing, found that there is no 50M optical fiber speed of our company. Then wrote a speed test report, submitted to Netcom, hoping to be very serious to deal with this problem. Computer room staff after testing, but also very helpless, network cable plugged into other servers, speed can reach very high, in the LAN download things on average 10M. But on my server download the same file, the average speed is only 6M, change the network card is still the case. This concludes that the problem is on my server. The problem is on their own server, not to mention the submission of the test report, how ignorant they are, now consider how to solve the speed problem? Are all two cards broken? In a helpless situation, start in the system midpoint point that. It was worth a try to find a place suddenly. That is the connection speed of the network card. Our current network card is 10m/100m Adaptive network card. Generally not to adjust the connection speed of the network card. But in this helpless situation, only one by one test. 100M Full-duplex mode selected. After restarting the server, the test speed, download LAN files have been back to normal, in other places on-demand video also significantly increased the speed of a lot. Server slows down unconventional solutions two scene my company's another server does not know from when began to change the special slow, Consultation machine room Yonder, people say very normal, may be our procedure problem. So we began to study each program carefully and study the memory occupied by each website. But studied for a long time, optimized a lot, the effect is still that, still slow unbearable. At this time, I have been using ping to detect the speed of the server, since the server slow down, Ping returned packets are always lost. Serious situation on average 10 times have 1 times lost packets, careful analysis of the phenomenon of packet loss should not be the problem of the program, can only be the problem of the circuit, in other places ping our server is still lost packet serious, this is the exclusion of our company network problem. Thought again is not the network card working time too long, aging, so request the room staff to change the network card again. The result is laughable, the room staff told me, after their test, found that the problem is a network cable, a new network cable, speed and return to normal. There is no packet loss phenomenon. May be in your server did not encounter problems, you will feel the above two methods is ridiculous, but the server is 24 hours running, it is impossible not to have hardware aging and other problems, I just hope that my own solution to become your future processing server a way of thinking.
