We have migrated last night everything to new hardware. More about the hardware.
Performances are boosted by at least 10x if not more, in general for all tasks/actions.
Earlier the rebuild of NodeBB took about 5+ minutes, now it is done within ~50 seconds frame.
GitLab reconfigure took 8+ minutes earlier, now it is ~10-15 seconds.
Backup procedures took 10-15 + minutes. Now is under 1 minute.
Next major step for upgrade would be quality USB 3.0 to Ethernet adapter.
