You can execute several statements to accelerate the INSERT operation after locking the table:Lock tables a WRITE;Insert into a VALUES );Insert into a VALUES (8, 26), (6, 29 );Unlock tables;This improves the performance by refresh the index cache to the disk at a time until all INSERT statements are completed. In general, there will be an overhead for refreshing the index cache to the disk for many INSERT statements. If multiple values can be inserted in one statement at a time, the displayed lo

memory. I can't doubt that I want Nb to run faster, but the 32-bit operating system can only catch 3 GB in nature, but it cannot be changed, so we want XP to "use" to 4 GB, and make Nb run faster, so there will be no money. SolutionWe hope to give 1 GB of XP to ramdisk and use ramdisk to accelerate Nb. What is ramdisk? Simply put, the memory is converted into a hard disk, because the memory speed is faster than the hard disk, and the I/O speed is g

The MAC OS x system has some very useful system features on the menu bar, and if you find that they are helping you a lot and want to do more on the menu bar, try the 4 software recommended below.

A friend who just used the MAC OS X Lion system asked me how to modify the Hosts file under the system, said online search a lot of methods do not work, as long as the edit Hosts file appears "You are not the owner of the file hosts, so there is no permission to write to the file" hint, to resolve this issue of permissions than More cumbersome, not easy to understand for users who just use Macs. So, with this tip, I'll share four ways to modify the Ho

in the second project cache when using Copy-on-write. Here, to update, you first create a copy of the database, update it on the replica, and, to commit, update the pointer to the original database to a pointer to the latest copy. If there is a failure before the update, after the restart or point to the original database, the equivalent of the transaction abort, if the update after the failure, after restarting point to the updated database, transaction success commit. But here it is necessary

1) Why can 32-bit systems use more than 4 GB of memory?As long as the CPU, motherboard, and operating system support and enable PAE (physical address extension), the physical memory address bus is 36 bits.2 ^ 36= 68719476736 = 64 GBIn addition,Current x64Instead of using a 64-bit address bus48 digitsSo the maximum memory size is 2 ^ 48.So, the current32-bit systems are not pure "32-bit"; x64 is not pure "64-bit ". 2) Why does Windows 2003 32-bit suppo
