Yes, exactly. Sure, it could be done with an in-memory buffer. And while it would help some people, it would help in much fewer scenarios compared to fleecing, because RAM is almost always more expensive/more limited than storage space. _______________________________________________ pve-devel mailing list pve-devel@lists.proxmox.com https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
