comprehensive evaluation of 24 fully-gigabit switches. During the overall assessment, the weight is: performance accounts for 60%, functionality accounts for 30%, and price accounts for 10%. Currently, 24-port full-gigabit switches with fixed configurations are divided into two categories: Pure Layer 2 and Layer 3.
Alcatel OmniStack 6300-24 has outstanding performance in four fully-gigabit switches with 2-layer and 24-port tests. Alcatel OmniStack ha

GB primary partitions. The specific method is as follows: first execute fdisk-l and you will see/dev/sda. If there are multiple hard disks, there may be sdb, sdc, etc, here I will show that there is sda1 (root partition of the existing system), sda2 (SWAP partition) and then execute fdisk/dev/sda. This is the prompt that you can enter m to see. Input n indicates to create a new partition and input p, because the installation system requires the primary partition because the primary Partition nu
Incredible. Remember that this really eight-core CPU is one of the fastest cell phone chips in World War I with Tegra4 and Yunlong 800. When Xiaomi 3 with Tegra4/Yunlong 800 was sold for 1999, the red rice note generation could only sell for 799. How can a model of the same level be so sold?Background:Tegra4 (Xiaomi 3), 4 core, Cortex-A15 architecture, frequency 1.8 GHz, performance ratio 3.5, single core performance 3.5*1800 = 6300 MIPS, four core pe

Server performance RAM: 4 GB/1067 MHz/DDR 3cpu: 2.53 GHz Intel Core 2 Duo insertion: 0.1 million 25 seconds after the same record is put, the TT file is more than 400 mb, however, MongoDB is 2 GB in size. Therefore, it is assumed that this is the completion of the MongoDB space pre-allocation to obtain records through the primary key: Every 0.1 million times 33 seconds through the Primary Key Update: Every 0.1 million times 25 seconds after 5 tests, we can obtain MongoDB performance indicators:

Centrino model and the non-Centrino wireless network card standard models. The advantage is that it eliminates the need for a PC card or USB slot and eliminates the hassle of carrying a PC Card or USB card at any time. At present, these kinds of wireless card in the price gap is not small, in performance/function is also similar, on demand and choose. (Figure IV)
