Jumbo Frame Pros

Jumbo frames extend the maximum frame length of Ethernet to 9K, which almost extends the previous maximum frame length by 6 times. The advantage of increasing the frame length is that it reduces the number of data packets in the network and reduces the extra overhead of network equipment processing packet headers. After testing, in the traditional Gigabit Ethernet, about 81,000 packets flow through the network per second, and in the network using jumbo frames, this number is reduced to 14,000. In a 10-Gigabit network, this contrast is even stronger.

The greatly reduced number of frames will surely bring performance improvements. Regardless of system throughput or CPU occupancy, jumbo frames have a great advantage compared to traditional Ethernet frames, increasing the data transmission efficiency by 50% to 100%.This significant performance improvement has allowed most manufacturers to incorporate 9000 bytes into the regular MTU size, making the jumbo frame size at least 9018/9022 bytes. Therefore, most Ethernet devices can support jumbo frames up to 9216 bytes.

Are SSDs or HDDs better for gamers?

Image
With the release of the PlayStation 5, SSDs have officially become the new gaming standard. A comparison of PS4 and PS5 load times — one with an HDD, the other an SSD — shows clearly just how much improvement an SSD offers. It’s only a matter of time before any new AAA game will all but require a solid state drive. Nevertheless, if you’re working with a tight budget, getting an HDD is more than sufficient, especially since SSDs mean significant space constraints. And even with an HDD, there’s a lot you can do to improve your computer’s gaming performance. Learn more here https://www.ankmax.com/newsinfo/1632698.html

When do you need SSD alignment in Windows 10/11?

Image
SSD alignment mostly refers to SSD partition 4K alignment because SSD adopt the smallest 4K sector in file system to save data. If the smallest 4K allocation units are not always aligned with the 4K pages in SSD, the performance of SSD could be affected. 4K alignment also is widely used in advanced formatted mechanical hard disk. 4K aligned partition better serves operating systems and offers higher performance. One may need to align Windows 10 after clone. There are some signs that show your SSD alignment not OK. For instance, known small file occupies large disk storage in data partition, or system programs and applications run slowly even if you just upgrade hard drive to SSD. If things continue this way, the number of unnecessary writing operations will increase dramatically, which shortens SSD lifespan eventually. ...

What Does Hard Disk Drive (HDD) Mean?

Image
A hard disk drive (HDD) is a non-volatile computer storage device containing magnetic disks or platters rotating at high speeds. It is a secondary storage device used to store data permanently, random access memory (RAM) being the primary memory device. Non-volatile means data is retained when the computer is turned off. A hard disk drive is also known as a hard drive. Learn more here  https://www.ankmax.com/newsinfo/1632698.html
