Test data of PostgreSQL running on FreeBSD and Linux
This afternoon I wanted to test DragonFly dports. I suddenly wondered why I didn't compare the performance difference between PostgreSQL in BSD and Linux. For this reason, I set some standards to compare the performance differences on different operating systems. I use the same hardware and software to obtain data more accurately. These tests are based on PGSQL9.1.
I was surprised when I tested it I

Affected Systems:FreeBSDDescription:--------------------------------------------------------------------------------CVE (CAN) ID: CVE-2012-1571FreeBSD is a UNIX operating system and an important branch of Unix developed from BSD, javasbsd, and 4.4BSD. The file (1) utility can test the classification of file System Objects Based on the file system, magic number, a
FreeBSD is an excellent UNIX operating system. It is famous for its excellent stability, security, and performance. It is one of the mainstream server operating systems. Not long ago, FreeBSD released a new major version FreeBSD 7.0, which added many outstanding features. Now we take the standard PC as an example to introduce the installation process of
Change work, mainly contact SuSE Redhat Aix These have the original service system, FreeBSD long not touched, and now quickly forget, yesterday under the FreeBSD 10来 play, found there are many new changes. So write a few articles about FreeBSD, hoping to let more people understand it.The environment is based on:Vmware 11 Please own BaiduFreeBSD 10:Http://mirrors.

Features are very friendly interface, easy to use, the hardware support is very comprehensive, is the most suitable for desktop system Linux distribution version.Gentoo, the Great Gentoo, is the youngest distribution in the world of Linux, and because of its youth, it is one of the reasons why Gentoo is known as the most perfect Linux distribution
The installation system is a complex process, one of the reasons is the variety of personal computer hardware, can be combined in a variety of ways, so it can cause complex installation problems.
Network Installation Method
In addition to using the installation CD to install FreeBSD, there are several other installation media to choose from, where network installation is also a very convenient way to install.

other messy things. There is also a machine that has been granted root permission many years ago. (Ironically, it was a Linux machine, not Microsoft, and the machine never took any safety measures, and the lab keeper's brother put a rootkit on it.) When we found it, we replaced it with FreeBSD, and the root code was kept by us, and the machine was never invaded again. )
The lab now has 10 Windows XP machines and a
Objective
We may have seen many Linux operating on floppy disk, can run on floppy disk FreeBSD instead of less, although there are PICOBSD, however, many times Picobsd does not meet our needs, then can we make a floppy disk run on the FreeBSD system? The answer is yes. I am maintaining a floppy firewall project, which is a firewall system based on FreeBSD and IP

Recently developed PHP need to use VI, but the PHP file needs to support Chinese, so consult colleagues, with the results.
It used to be connected to the FreeBSD server using putty, but it seems to be problematic to enter Chinese, so using f-secure SSH client 5.4, SSH client can also be more than putty, but not so convenient.

System environment:
Because the file system is a very important part of the system, the task of maintaining the file system is also very important. This task includes checking, fixing the file system, and adjusting the tree to fit the changes in the system, adding new storage devices, etc.

There is no problem with the file system when using FreeBSD under normal circumstances. However, in some cases, if the computer's power is cut off without a nor
In actual work, we often encounter the requirement to connect two local area networks in different locations. The use of FreeBSD IPSec tunnel method can easily connect two local area networks, and has good security. Here's a case to tell how to connect two local area networks in this way.
Assume the following network structure:
The two FreeBSD machines are configured with firewalls of two subnets, and I
Because FreeBSD is a multi-user system, it requires the administrator to do day-to-day maintenance, especially as a network server system, once because of lack of maintenance caused by downtime failure, will cause great losses. Even for a single user of the FreeBSD system, but also to perform these indispensable maintenance tasks, only because the system to personal use, then the maintenance requirements ne
Top is designed for Linux. The free concept in the FreeBSD VM is quite different from the other OS, and using the top to view RAM memory is meaningless for FreeBSD. The correct way is to look at the Vmstat.
