Today, when I tested how many MySQL instances a machine can support, I accidentally found that MySQL5.5 had a good support for multiple cores. I didn't say that MySQL was a huge one.

MySQL 5.5 supports multi-core CPUs. When we test how many MySQL instances can be supported by a single machine today, we accidentally find that MySQL 5.5 supports multiple cores quite well, in the past, I was not talking about a major defect in MySQL. Is it impossible to make good use of the CPU? It seems that MySQL 5.5 is still good. The test tool is sysbench, test-mode = oltp, And the buffer for each instance is 12 GB. About 36 GB of data is generated by sysbench, and buffer accounts for 1/3 o

-way server products. The third digit is the number: The server that represents this server is the first generation.Currently Dell's newest server is the 12th generation, so this number is 2Last digit, 0 means Intel's cpu,5 representative is AMD's CPUIn addition, for some special servers, a few letters will be marked at the end to differentiate. For example, r720xd on behalf of this server can configure ultra-high-density disk (2U configured up t

Label:Recently there is a business writing far greater than reading, reading is also focused on the recent write, which is not very suitable for the use of LEVELDB storage.Ssdb is the LEVELDB Redis Compatibility Protocol package, and realizes the master-slave synchronization, the source code is not much easy to read, mainly to the Redis command encapsulation, Get/set not say, Leveldb is ordered, compared to redis through the Scan Traversal command, the use of ordered list, The Hset is also store

It can be seen that in the case of 1246 instances, tps is basically linear growth. Although there is no absolute adequacy, there may be other considerations in the actual situation. It can be seen that in the case of 1/2/4/6 instances, tps is basically linear growth. Although there is no absolute adequacy, there may be other considerations in the actual situation. The usage of MySQL 5.5 to multi-core cpu recorded in the previous article, click here (). In fact, the main purpose of the ori

/sys/net/core/rps_sock_flow_entries 32768Summary below:Rps/rfs is primarily for single-queue NIC multi-CPU environments. Although these virtual queues are supported, they are software simulations. It is strongly recommended to use a network card that supports multiple queues.Multi-Queue Multi-interrupt Nic can also use the RFS RPS after using the SMP affinity, where he is more like a receiver's mediator, maximizing the CPU cache.Some of their own understanding, if there is no place, please frien

The company's ERP system has a large amount of data, with 40 GB of data and 90 + concurrent users and 1000 + connections. The original IO performance cannot meet users' operation response requirements, and report query is slow, all the indexes have been done, and the index is re-built once a week, but the problem still cannot be solved. To this end, the company purchased the dell poweredge R720xd server, which supports two arrays and 24 hard disks, du
