History I created a simple application for logistic purpose based on Django, PostgresSQL, and Postgis. This is a service receiving a position of a truck and place it on the map. Service is really simple and uses a virtual machine with small performance. The main problem of the current solution is a small performance of this cloud server. Most of the cloud providers use LAN for attaching virtual server's drives. As result speed of disk I/O is really small. root@sergiy:/home/serg# fdisk -l Disk /dev/xvda1: 20 GiB, 21474836480 bytes, 41943040 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/xvda2: 1 GiB, 1073741824 bytes, 2097152 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes root@sergiy:/home/serg# hdparm -tT /dev/xvda1 /dev/x...
