error. This usually indicates that the add (element already exists) or replace (element does not exist) stores data failure or that the element is already in a deletion sequence (deferred deletion). Memcached::res_notfound Element was not found (when through get or CAS operations). Memcached::res_partial_read Local network data read error. Memcached::res_some_errors An error occurred while the multiple key was being fetched. Memcached::res_no_servers The server pool is empty. Memcache

MemcachedHave a Statscommand, which allows you to view a number of status information for the memcached service. use the following methods:The status information for the current memcached service is displayed by entering the Telnet hostname port number directly on the command line, connecting to the memcached server, and then entering the stats command when the connection succeeds. For example in my native test is as follows:StatsSTAT PID 1552 STAT

there is no serialization, it is not saved to the cache, there is no record.Get_hits: Indicates the number of times the data was successfully obtained.Get_misses: Indicates the number of times the data failed to get.Evictions: The number of cached objects removed from the cache in order to free up space for new data items. For example, objects that are removed based on the LRU algorithm when the cache size is exceeded, as well as expired objects.Bytes_read:memcached The total number of bytes th

The program is written by PHP a websocket server, the client is connected to send messages continuously, the service side is responsible for responding to requests. Tested: Once per request of client, server PHP consumes time of Microsecs to MICROSECS (message size is different). The server is a single core, 30 clients, using top to view PHP processes occupy CPU around 3-5%, load average 1 minutes load display 0.05 or so. Basically meet expectations.

[1] Physical CPU: The number of CPUs on the slot in the actual server. Number of physical CPUs: There are several physical IDs that can be counted without duplicates. [2] Logical CPU Linux users are certainly not unfamiliar with the/proc/cpuinfo file. It is used to store CPU hardware information.The information content lists the specifications of the processor

In electronic technology, the pulse signal is a pulse signal continuously sent at a certain voltage range and at a certain interval. The interval between pulses is called a cycle, and the number of pulses generated per unit time (for example, 1 second) is called a frequency. Frequency is the metering name that describes the number of pulses that appear in a periodic cycle signal (including a pulse signal) per unit time. The standard unit of measurement for a frequency is Hz ). The system clock i

How does the CPU look at performance? This is a problem that friends of computer enthusiasts often ask. Today, the computer Pepsi network finally brought the CPU ladder Figure 2016 the latest version, through the latest CPU ladder diagram, can fully understand the computer processor performance.
