results may be available, too short time, I will find a physical machine for you to conduct more detailed evaluation, the hardware configuration of the virtual machine is as follows;

I think this configuration should have little impact on the performance of the virtual machine.
memory, refill can be avoided. Intel's non-temperal method serves this purpose, this is the optimization idea of reducing replication in this article.
Some other tips in the Code are not described in detail. If you have any feedback, I will write a further answer. For details, see the following code.

Every time fedora is installed, everyone will set it up. Here are some of my favorite: Updates
Yum Install Yum-fastestmirror-y
Yum Update-y
Yum Install Gnome-tweak-tool-y
After the system upgrade, the general will appear new kernel, this is to restart the system, into the new kernel to remove the old kernel, you must not update the finished directly to delete, will be tragic.
Rpm-qa | grep kernel #查看已安装的内核
Uname-r #查看当前使用的内核
Yum Remove kernel-#删除不需要的内核, such as: Yum Remove kernel-3.1.0-7.
never met before. Baidu, there is really a classmate met, the situation and I was also under 64 fedora with the SDK, said ADB and AAPT need 32-bit library, really weak burst, since do not support 64 why still write support 64!
Altogether missing 4 libraries, one is ld-linux.so.2, one is libcurses.so.2, the other is libstdc++.5 and libz.so.1
The installation method is, choose Yum to find out which package, and then install the package:
Copy Code code as follows:

This article mainly introduces how to use LIMIT for paging in MySQL. The author lists three methods and provides tips for page jumping and other common problems, if you need a friend, you can refer to a friend who reads this article and says that his MySQL has become slow. When asked. Indicates a MyISAM with a single table exceeding 2 GB. The answer to the spam.
Simple answer: change to a strong server. It works very well for changing servers :)
.........Finally, the slow query is obtained:

In the s battlefield script uploaded by Cao, the addition of our army is somewhat different from that of the enemy and friends army. In the settings for the appearance of the enemy and friends army, the first parameter is that the character is in chara. the serial number in JSON, and the arrival of our army is determined by the personnel of the selected army. Therefore, the first parameter is the seri

Today, a friend of mine said that his MySQL has become very slow. When asked. Indicates a MyISAM with a single table exceeding 2 GB. The answer to the spam.

.........Finally, the slow query is obtained:
SELECT * FROM pw_gbook WHERE uid='N' ORDER BY postdate DESC LIMIT N,N; SELECT * FROM pw_gbook WHERE uid='N' ORDER BY postdate DESC LIMIT N,N;
For example
:[Email protected] ~]# chmod 664 a.txtAccording to the above rules, rwx together is 4 2 1=7, a file with a rwxrwxrwx permission, the value is 777, and the file "---------" with a completely open permission is represented as 000. Here are a few examples:-RWX------: equals the number represents 700.-rwxr-r--: equals the number represents 744.-rw-rw-r-x: equals the number represents 665.Drwx-x-x: equals the number represents 711.DRWX------: equals the number represents 700.In text mode, you can exe
