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. After I tested it In Debian Linux, I was surprised by the results. So I did a

and Devicemapper direct LVM. For our current plan to use Docker on-line service, mainly focus on the files from hundreds of KB to a few MB size, just consider reading, write the operation is mounted volume way, not directly written in the container. In terms of reading, Devicemapper has a slightly better performance than Btrfs. In the stability of the comparison, because the offline test can not completely imitate the scene of the line, the initial plan to go online when a part of the container

restored through the log server, the file system stops service during the recovery process. glusterfs and sheepdog are network-mounted structures and are born with no separate faults. All of them are reliability-oriented, we should consider using glusterfs and sheepdog. Comparison of stability: Drbd, mfs, and glusterfs are all mature file systems. They have esta

, it also provides an intuitive and easy-to-use Web interface. Both FreeBSD and FreeNAS support ZFS, which is like NTFS and FAT32. Compared with NTFS, ZFS has many advantages, such as the maximum file and partition size, automatic repair, and RAID-Z, which are not restricted for home users. Although ZFS targets enterprise and commercial users rather than consumer

Linux2.6.19 kernel released in 2008. When the 2.6.28 kernel was released, EXT4 ended the development and began accepting users ' use. It seems that ext will become synonymous with Linux file systems. However, when you read many articles about EXT4, you will find that you have mentioned btrfs in unison, and that EXT4 will be a transitional file system. Ext4 's author Theodore Tso also praised Btrfs and believes Btrfs will become the next generation Linux standard file system. ORACLE,IBM, Intel a
