I'm only getting 22MB/s when I transfer files from my Win7 PC to my WinXP PC versus 100MB/s from Win7 PC to Win10 PC SATA600 HDD. I've set SATA to AHCI in BIOS. Can I improve the transfer speed? Or is this normal for 10 year old hardware.
CrystalDiskMark shows I can get 130MB/s on the WinXP 2TB HDD. Iperf test shows 100MB/s transfer and 850Mbps bandwidth. WinXP CPU usage is 5% during transfer.

I just tested on my XP machine (fully patched using Windows Update) with a dual core Core i3 3210T . I get over 112MB/second over FTP download and 56MB/second in Windows file sharing (SMB using SAMBA on a Linux server) through the integrated Realtek Gigabit NIC . TCP Optimizer optimization does nothing to change that .

On the same machine, when running Windows 10 x64, I get over 122MB/second in both FTP download and Windows file sharing (SMB using SAMBA on a Linux server) .

I can't really say if you should expect more speed on your XP build, but my impression, so far, is that Windows XP "sucks" at file sharing (SMB) throughput .

Can you recommend a secure ftp server for WinXP?

I don't believe that I have ever run an FTP server under Windows XP (or any version of Windows), AFAICR, so I can't suggest anything there .

As for the secure aspect, neither Windows XP or the FTP protocol are particularly secure. I would not run either in a scenario where the Internet could reach them (unless I explicitly wanted to FTP server to be public) . I do allow outbound Internet connections from my XP machine, for now, but I am very selective about the few WEB sites that I do access .

That said, if you want an FTP server, I suggest

- Running it on a machine with a modern OS (more choices)
- Making it not Internet accessible (should be the case by default if the machine running is behind a home gateway/router)

How do I make WinXP/98/95/NT not internet accessible but still LAN accessible? All my computers are connected to an ethernet hub which is connected to an internet router.

Don't give the client PC a (valid) gateway address. Blacklist the client PC's NIC MAC in the router. Even better, if you have the equipment and know-how, make a separate VLAN for those devices.

Oh, and if you're still using a hub in 2021, do yourself a favour and get a switch. A decent Gb switch costs less than EUR 15 these days. If you really like the nostalgia of collisions in a shared domain resulting in collapse of performance as soon as multiple devices try to access the medium at the same time, use the hub for the pre-2000 computers, but get everything more recent onto a switch. Even a 10MbE switch would be an improvement over any hub 😮

I have Eero Pro. I have blocked my vintage computers on the app, hope it also blocks incoming connections to it as well. I'll research on Gb switch. I didn't know there are small consumer versions available. Most I've seen are large rack mountable on ebay.

Edit: Looks like my "ethernet hub" TL-SG108 is a Gb switch.

Sorry to bump an old thread, but i have the same problem with an XP machine that's used for VHS video capture. It's connected to a Mac Pro 2019 with a direct ethernet cable between a thunderbolt gigabit interface on the mac side, and onboard gigabit on the XP/Asus P8P67LE side.
And although both operating systems report "1Gb/s", i can only send files to the XP PC via SMB at 20-30MB/s, and about 50MB/s from the PC to the Mac.
And although I've put this problem on hold for now, this reply might at least help to eliminate variables for future people doing variable elimination on this issue.

With Win2000 and onboard Realtek Gb ethernet I get around 40MB/s. With Realtek Gb ethernet on a PCI card I get 25MB/s. Not sure if the NICs, the switch, or the SMB version 1 protocol itself is more of a limiting factor. I used to have a better switch but it died in a power outage.

Tweaking registry settings might help also https://www.techtarget.com/searchvirtualdeskt … kstation-Tuning

SMB performance under XP is not great versus newer Windows versions. You might want to set up an FTP server on the MAC instead.

Also, if your capture card and related software could be made to work reliably under a 32-bit install of Windows 10 or Windows 7, you might get better SMB performance that way.
