Fixing Synology DS413 slow transfer speeds
I have an ageing Synology Disk Station 412 NAS. It used to be capable of very reasonable 100MB/s transfer speed. At some point, I enabled share encryption, which reduced transfer speeds by about half. It was chugging along like this for quite some time but then noticed that speeds got even slower. After a quick test, I found that upload to an encrypted share was lingering at around 10MB/s, downloads were maybe double of that.
