starting a test of the experience speed and performance of a cloud host product. Of course, also want to have used this product netizen can leave a lot of comments to the considerable evaluation, convenient for other users reference. First, Ex-cloud official website The code is as follows Copy Code VPS Official Website: https://ex-cloud.jp/zh/vps/ It seems that businesses in order to cater to Chinese users is also

NTFS format, can for C disk expansion. If your computer's hard disk was previously partitioned in NTFS format, you can continue with the next step at the bottom, as shown in the following illustration. Note: If the computer partition is in FATA32 format, the C disk cannot be extended through the partition assistant. The next step is to choose which disk space to release some of the extended to C, here is mainly from D, E, F, and other non-C disk space, extended to C disk, you can

Although the BD Blu-ray Disc capacity is huge, single-layer and two-tier can reach 25GB, 50GB respectively, but in the burning time, it is not necessarily guaranteed to fill all the space. Microsoft today confirmed by a KB2575215 Knowledge base article that when trying to burn 23GB data to a bd-r single burning disk, or to burn 46GB data to a bd-r two-tier burning disk, the burn will not succeed and the following error message appears: "There was a

rebooting, such as when installing certain software, installing patches to the system, repairing and changing hardware devices, or modifying BIOS settings, be sure to shut down or restart the computer. If you need to leave the computer in the process of work, then you can use sleep function, on the one hand can save electricity, on the other hand can quickly resume work. At the same time, after sleep, the computer will only have memory power to keep the working state of the data, while th

mention, they found that in the TC insert 160 million 2-20KB data, write performance began to drop dramatically. It seems that when the amount of data on the billion, TC performance began to decline significantly, from the TC author's own Mixi data, at least thousands the amount of data has not encountered such a significant write performance bottlenecks. Flare, which is an improvement on TC and TT, mainly supports scalability. MongodbTo meet the mass storage requirements, MONGO mainly solve t

With the improvement of a large number of default options, MySQL 5.6 has significantly fewer options than previous versions need to tune. In this article I will describe the configuration items that need to be optimized. InnoDB settings 1.innodb_buffer_pool_size --The default value is 128M. This is the most important optimization option because it specifies how much memory InnoDB uses to load data and indexes (data+indexes). For dedicated MySQL servers, this range of 50-80% is recommended as

store high-definition video is only about 50GB, so videos that don't compress at all can not be stored, let alone send each other. 2. Compression of simple black and white images Suppose the data for black and white images are as follows, black pixels are encoded with 1, and white images are encoded with 0: The black-and-white image has a size of 16x8 = 128, so it needs 128bits to represent it. If we start with 0 and save only the number of columns

When this restarts, the cluster status is always yellow and there are some unassigned shards. The cluster configuration can be done without downtime at this time.

Two scenarios of database migration: https://www.cnblogs.com/mcgrady/p/7614491.htmlProgramme I1, first package the database files on the source server (including the MDF and LDF files) and copy them to the destination server.2, unzip, and then attach the database on the target serverSummary: Suitable for large databases (50GB or more), need to quickly migrate data, and mobile hard disk space is large enough.Back to top scenario twoRestore after backup

interface display is 10.04GB, if it is 40G you enter 41116, then the Windows Explorer display just 40.01GB. Therefore, the above formula is not very accurate. The most accurate hard disk partitioning algorithm is as follows (from a web search): The hard disk generally has 255 heads, 63 sectors, so the size of each cylinder is: 512byte x 255 x 63=8225280bytes =7.84423828125 MB If you want to divide 40GB, then 40X1024MB=40960MB Requires a cylinder number of 40960÷7.84423828125=5221.66 Take

The number of virtual addresses managed is less due to the same memory size as the huge page is used.The TLB entry can contain more address space, and the CPU's addressing capabilities are enhanced accordingly.C, decreased page table overheadReduce page table load, for normal page, each entry

Label: I. Overview 　　MongoDB is a database open source project based on distributed file storage. Written in the C + + language , it is designed to provide a high-performance, sustainable data storage solution for WEB applications. MongoDB is a product between a relational database and a non-relational database. The data structure it supports is very loose and is a json - like bjson format, so you can store more complex data types. Mongo's biggest feature is that the query language he supp

Bson supports inserting document objects and arrays into other document objects and arrays as well as JSON, extending the JSON data type. For example: Bson has a date type and a bindate type.Bson is likened to a binary interchange format, like protocol

Transaction log files are successfully shrunk in database mirroringHow do you shrink a transaction log file when the database is already running in database mirroring?We have a product database found that the transaction log file has reached 60GB, and the database itself is only 30GB. The transaction log file needs to be shrunk.After a week of observation, on average there is no 1.5GB log, 99% of the log is produced in the evening, the weekend has a 16GB log, it seems that most of the non-work
