Fedora13 starts Acceleration

Btrfs is so envious that I made up my mind last weekend to replace Ubuntu10.04 with Fedora13, so I had to spend less time sleeping on it. Ubuntu10.04 is indeed very good, very good, and first-class startup. People like me are very satisfied. Since Fedora was too slow, I gave up on it. According to the comments on the Internet, a major feature of Fedora13 is that it is faster to start, and btrfs is launched. The result is tragic. It takes at least 40 seconds to start the process.

Ubuntu 10.04 is indeed very good, very good, and first-class startup. People like me are very satisfied. Since Fedora was too slow, I gave up on it. According to the comments on the Internet, a major feature of Fedora 13 is that the startup speed is accelerated, and btrfs is started. The result is a tragedy. It takes at least 40 seconds to start the process. 40 s. I feel like I can start three Ubuntu instances. Based on experience, ora has a lot of services, so it closes a lot of services that are not needed, and there is almost no improvement. It's really annoying.

If you press F2 during the startup process, you will find that starting udev has stopped for a lot of time. Set/etc/udev/rules. d. I can't eliminate some of the services that I can't use, such as the hpc ip (hp printer, I don't have a printer). The results still don't work, or I just want to speed up the work. I noticed that/dev /. udev directory has a failed directory, there is a file eth1_rename, because my computer dual Nic, as to why the file appears, it is not clear, but certainly related to the persistent-net.rules, rename the file. Restart, haha. The speed is fast. It can be used together with Ubuntu 10.04.

In fact, the reason for this problem is that my motherboard suddenly changed the Mac addresses of the two NICs on the motherboard to the same after updating the bios. Udev may operate based on the mac address. Turn off a NIC in the bios. The above method is only valid once. Because the file is dynamically generated, you can modify the RULES_FILE variable of/lib/udev/write_net_rules. You can just generate the. rules file. But how can I modify the NIC mac of my motherboard? I don't know. I didn't find any related tools. If anyone knows, please let me know.
