This is a creation in Article, where the information may have evolved or changed. Speed limiter Before seeing this two speed-limiting methods of golang concurrent programming, I think the way sleep waits is not particularly good, and it takes longer to wake up threads. and 1s within the request can only be evenly arrived, such as an instant to N, then only one can immediately return, the rest can only wait. AmendedAccording to the instructions, whethe

divided into two chips: internal and external. The internal chip second-level cache runs at the same speed as the clock speed, while the external second-level cache is only half of the clock speed. The L2 high-speed cache capacity also affects CPU performance. The principle is that the larger the cache capacity, the better. Currently, the maximum CPU capacity of a household is kb, the CPU L2 cache on servers and workstations is 256-1 MB, and some are 2 MB or 3 MB.

an adhesive layer (glue) between the logical API layer and the actual implementation layer. As the neutron project evolves, the more loving plugins are introduced, they come from various open source projects and communities (such as Open VSwitch and Opendaylight), and the vast majority of vendors (vendor, such as Cisco, Nuage, Midokura And so on). At the beginning of the Kilo development cycle, Neutron had more than 10 plugins and drivers, including core plug-ins (cores plugins), ML2 mechanism

very low latency and a hit rate of up to 95%. The high speed transfer capability of L1 cache beyond the K8 architecture allows the L1 cache capacity of the k8l architecture to be reduced to 1 32KB indication cache + 1 32KB data cache, thereby increasing its hit/turnover rate. The K8L architecture processor has a growth of more than 80% L1 cache system performance over the K8 architecture processor, while AMD is also considering keeping the L1 cache at 1 64KB indication cache + 1 64KB data cache

1. Why do I need VxlanThe average number of VLANs is only 4,096, unable to meet the needs of large-scale cloud computing IDC, and why IDC needs so many VLANs, because most of the IDC internal structure is mainly divided into two kinds of l2,l3. L2 structure inside, all servers are in a large LAN inside, Tor Transparent L2, different switches on the server interoperability by MAC address, communication isolation and broadcast isolated VLAN, gateway in

A level three cache is designed to read data that is not hit by a level two cache, where only about 5% of the data in a CPU with level three cache needs to be called from memory, which further increases CPU efficiency. It works by using a faster storage device to keep a copy of the data read from a slow storage device, when it is necessary to read and write data from the slower storage, the cache can enable the read and write action to be done on the fast device first, so that the system respond

instantaneous requests may be allowed to cause problems, so in some scenarios it is necessary to reshape the burst request, which is processed as an average rate request processing (such as 5r/s, which processes a request every 200 milliseconds, Smoothed the rate). At this time there are two algorithms that satisfy our scenario: the token bucket and the leaky bucket algorithm. The guava framework provides a token bucket algorithm implementation that can be used directly.Guava Ratelimiter provid

32-256kb.　　The L2 cache (level two cache) is the second-tier cache of CPUs, both internal and external. The internal chip level two cache runs at the same speed as the frequency, while the external level two cache is only half the frequency. L2 cache capacity also affects CPU performance, the principle is that the bigger the better, now the largest home CPU capacity is 512KB, and the server and workstation with the CPU L2 cache up to256-1MB, some up to 2MB or 3MB.

In fact, the project presented by the Huawei Israel technical team is still a subject of great interest to developers in the Internet sector. The Dragonflow project was submitted in 2014 and 2015, and has now be
