I'll start this off by giving some background and specific bullet points so that we can quickly eliminate some of the first things that may come to mind (and have been repeated in numerous other posts of people complaining of this same issue) when trying to troubleshoot this issue of extremely slow imports over a network from a NAS drive.
1) My NAS is a Buffalo LS421DE hard-wired into my cable modem/wireless router, containing about 30,000 files in my music library.
2) Media Center 23 (32 and 64 bit versions) on my Windows 10 PC is importing at the rate of about 1 file every 2 minutes. It's been running for over 24 hours and has only imported about 5000 files.
3) Media Center 20 running on my Mac Mini over the same WiFi can import my library within 15 minutes
4) Importing my library in other free applications such as Media Monkey and Sony's Media Go can also perform an import in under 15 minutes under the same conditions
5) The import in Media Center 23 on Windows 10 is showing large periodic spikes in network activity during the import, despite the very slow import speeds. There are times where I can see it using up to 200 mbps. Interestingly, while streaming FLAC files with Media Monkey, bandwidth never exceeds 7 Mbps. It seems as though Media Center is accessing other network resources, since my NAS can't even transfer at a rate of 200 Mbps. General network traffic for Media Center also seems very high during the import for such a slow rate of progress.
6) After reading through posts and the Wiki, I completely disabled Windows Defender real time protection, and this did nothing to improve speeds.
What are some other suggestions I can try here? As it is now, this is completely unusable to me. I do not plan on waiting 3-4 days for my library to import.
Thanks,
John
