Een aantal dagen geleden had ik de volgende post al gedaan op het
internationale forum, daar bleek ik geen respons te krijgen. Hoop hier meer te horen, of dit normale snelheden zijn en of hier nog iets aan te tweaken is.
Hi,
this post has been edited with an update, see belowI'm experiencing lower transfer speeds than expected with my DS-107+. Today I replaced my old 100Mbit switch for a high performance gigabit switch, but it didnt help. According to
this chart, my device should be able to read at an average speed of 27 MB/s, while my setup jumps around a
6 MB/s while downloading a big file (few gigs). I know their test method is different, as I believe they use FTP while I'm using "my network places" in Windows, but still. I also did a download test from another PC in my network, then it goes around 23 MB/s, so I guess my PC and network can handle it.
Am I missing some setting, or is something wrong?This is my setup:NAS: Synology DS-107+, firmware 2.0-0640
HDD:
Western Digital RE2 500GB (WD5000YS)
Switch:
HP Procurve 1400-8G (Gigabit with up to 9k jumbo frame support)
PC NIC: Onboard Gigabit LAN adapter of Nvidia nForce 4 Ultra chipset
PC OS: Windows XP Prof 32bits
Monitoring software is DUmeter 4, also tried Netlimiter2 Monitor, giving same results.
The LEDs on the switch says all connections (except for the internet modem/router) are in full duplex, at gigabit speeds.
I tried setting the NAS and NIC at 9000 and 4000 jumbo frame packet size, but this didnt help. I even think I got the best results with the standard 1500.
All else I will try is change the NIC for a nice Intel Pro/1000PT gigabit PCI-E card, which I think will deliver better results.
I'll also replace my cat5 UTP cables for cat6 cords. Not that I think this will matter, but I need new cabling anyways
Thanks in advance!
EDIT::
Errr... WOW. I just tested the speeds using FTP... huge difference; 22.5 MB/s! And when I changed the MTU from 1500 to 9000 jumbo frames, it jumped to 33MB/s!
I guess the NAS has a problem using the "Windows network places protocol" (how is it called?). Or is there still a way to improve these speeds? The protocol itself is not the limit, since the test goes fine ading from another Windows PC. Now I'll have to start a seperate FTP-program whenever I want to transfer a file at high speed. This is a shame, as the-windows-way of navigating feels the most logical and is integrated in the programs.
Now what is the best way/protocol to open a huge HD video file (without downlwhen downlooading the whole file first)? Currently I use "my network places", opening a file with Windows Media Player Classic (MPC), auto-loading an *.srt file for subtitles.
