Linux multicore bound hardware interrupts to different CPUs (IRQ Affinity) turn

Hardware interrupts occur frequently, is a very CPU-intensive thing, in multi-core CPU conditions if there is a way to allocate a large number of hardware interrupts to different CPU (core) processing is clearly a good balance of performance. Now the server is still multi-CPU multi-core, multi-card, multi-disk, if you

If there is a way to allocate a large number of hardware interruptions to different CPUs (cores) under multi-core CPU conditions) processing clearly balances performance well. Currently, multiple CPUs, multiple NICs, and multiple hard disks are not supported on the serv

Different types of NAT have different Penetration Effects

stun" published by the author, I spent a lot of energy explaining that iptables is theoretically classified as hierarchical Nat rather than port restricted cone.Many people (including when I first studied the STUN Protocol) have doubts about this, that is, for STUN Protocol itself, port restricted cone andAlthough the ing mechanism is a little different, they all have port-restricted attributes. At first glance, the two areNAT traversal features are

Analyze hardware bottlenecks that affect streaming media server performance "retransmission"

to read raw dataThe original streaming media files are mainly stored in local hard disk, NAS or SAN storage devices. Regardless of the way data is stored, the ability to read raw data files directly affects the performance of the server. The requirement for read capability is very much related to the number of business types and user requests. Live streaming has the lowest requirement for data read rates,

#运算符, different pointer types, arrays and pointers, pointer operations, heaps, stacks, static extents, read-only, subscript vs pointers

areaStatic intc =0; Global (static) initialization zone P1=Char*) malloc (Ten);//Heap }To find the number of elements in an array:DIM (a) = sizeof (a)/sizeof (*a);Subscript vs Pointer:1. Theoretically, when the pointer moves in a fixed increment in an array, its efficiency is higher than the code generated by the subscript (the multiplication is time-consuming when the index is subscript).2. The performance is better when the pointer increment is 1 and the
