[ https://issues.jboss.org/browse/JBDS-3748?page=com.atlassian.jira.plugin.... ] Denis Golovin commented on JBDS-3748: ------------------------------------- More accurate calculation for required disk space: * Installer 1.6G * Installer unpacks contents to temp folder + 1.6G * Target Folder after installation 2.7G * Copy of virtual machine image in C:\Users\eskimo\.vagrant.d\boxes\cdkv2\0\virtualbox + 1G * Virtual machine files in C:\Users\eskimo\VirtualBox VMs\rhel-ose_default_1460383456479_40322 + 3.5G It is about 10G of disk space taken right after installation. Then JBDS starts and creates workspace + 0.2G. Windows should have enough free space on disk for swap file minimum/maximum file size recommended is RAM size/3 x RAM size, so medium would be 2 x RAM Size. User also needs space for sources + 5G. Considering all these numbers I would suggest: 1. Minimum configuration: 8G RAM; 10G + 2 * 8G + 5G = 31G; CPU Intel i3 2GHz 2. Recommended configuration: 16G RAM; 10G + 2 * 16G + 5G = 47G; CPU Intel i5 2GHz or better -- This message was sent by Atlassian JIRA (v6.4.11#64026)
