In Linux, the partner algorithm divides all idle pages into 10 block groups. The size of blocks in each group is the power of 2. For example, the block size in group 0th is 20 (1 page), the block size in group 1st is 21 (2 pages), and the block size in group 9th is 29 (512 pages ). That is to say, the block sizes in each group are the same, and the blocks of the same size form a linked list.

We often say that the design should be fresh, concise, and clear at a glance. Recently we have seen a trend towards flattening the design of Shixing. Today we will share with you the design of this type of page-the design of the pricing page. Many times, when you jump from the homepage to the pricing page, you feel like you are coming to another website. The importance of the pricing page is self-evident. If you want a higher conversion rate, you may wish to spend more time on it.

large number of packets because these include invalid TCP Timestamps. The temporary quick solution is to use the following command to disable the TCP timestamp:
Sysctl-w net. ipv4.tcp _ timestamps = 0
This immediately caused the package storm to stop. However, this is not a permanent solution because the TCP timestamp is used to measure the round-trip time and assign the delayed packets in the packet stream to the correct position. This will become a problem during high-speed connection, and th
