Access folder on C is much slower than shared folder
First of all, it's my first question in NAS community, I'm a newbie to Readynas, but have been networking since WIN 3.11 and Novell...so I do understand a little old network concept :oops:
Last month, I have bought two Readynas, Ultra 6 and Ultra 2, both connected to Dlink DGS-1008G switch, copy (though backup) from nas to nas speed is about +70M/sec. Which I'm more than satisfied 8)
From my Dlink DIR-655 Gigabit router connected laptop (SSD drive) to NAS is about +60M/s, so DIR-655 does support jumbo frame, just couldn't find where to set up it....(am I right?)
The slow down occurs when I'm showing our baby's photo to my wife on wireless connection (300Mbps, 5Ghz 802.11n (Dlink DIR-628 + Intel 5300AGN) , I tested the real speed by "fastcopy", it's about 6M/s, that's normal on 300M wireless. But open the photo on folder "Media" is 10 times faster than open my another folder "Photo" on C root.
"Media" has public access shared on, "Photo" is not. use Fastcopy to copy the same size folder took similar time , but I can see the different in the first few seconds, "Media" is 4-5M/s in the beginning, but "Photo" starts from 0.8M/s in the beginning.
Both test and all my networked computer are Windows 7 Ultimate, so I used CMD and type this to access Volume C:
net use \\READYNAS-U6\C /user:Admin
I use Acdsee 2.42 to view pictures, those photo are sized from 500k to 3M, I can see the thumbnail showing speed is very different on those two folders.
Is it possible that ACDsee need to "input Admin pass" with NAS when each file opened? I have tested open them in Windows picture viewer, but seems the same. So is it because of Windows 7 bad network protocol? I know someone get better performance on Win2K...but well....
I have studied before buying Netgear Readynas, the BIGGEST reason is this informative community and 3rd party add-ons. I hope it gets better day by day.
Sorry for my bad English, as it's my 2nd language... :wink:

- umm, anyone can help? or had similar problems?
- Small files (like photos) will have slower transfer speeds than big ones.
I suggest setting ACDsee aside for now and focusing on transfer speed.
Can you create a test subfolder in both shares (with the exact same files) and report back on transfer speeds?
BTW, why are you accessing C on the NAS instead of accessing the share? - The problem confusing me is because of the difference, ACDsee has no speed problem on Shared folders, just like access my local harddrive, (8M/s), I open a jpg sized 7M took me only 1 second, just much slower (3 second) on other non shared folder on root C.
The reason I need to access other non-shared folder is because my wife has made a terrible mistake before, she deleted the share on Readynas Frontview, without realize that it will also destroy the data and that folder. and I don't want to share everything on LAN, especially when you have a little boy at home. :evil:
Well you can set up shares to read-only, and also change the admin password.michaelche wrote: The reason I need to access other non-shared folder is because my wife has made a terrible mistake before, she deleted the share on Readynas Frontview, without realize that it will also destroy the data and that folder. and I don't want to share everything on LAN, especially when you have a little boy at home. :evil:
I am thinking that your current approach is not child-proof.- Thanks StephenB, I agree， to make a network Child-proof is a lift time project.... 8)
back to the topic, I did a copy test: (via wireless but I didn't move the laptop around while test)
for 1GB single file, it took 168 sec copy to my desktop from NAS shared folder, but took 172 sec if from non-shared folder. I can see delay in the first few seconds in non-shared folder.
for 1040MB (233 files) file folder, it took 190 sec from Shared folder, took 262 sec from non-shared folder!! When I use NX viewer to open them in different location, the thumbnail opening speed has big difference, non-shared folder is 3 times slower.....
Read-only folder is not practical for me, as I need to edit them all the time, I do have backup in different physical location, I understand NAS is never a place to store priceless data. - Is it practical for you to use a different logon than your wife? If so you can give her different access rights from yours.
I suspect that you are correct in thinking that the NAS is treating the non-share access a bit differently. There might be no way to fix this.
BTW, you can also hide shares, which might be similar in effect to what you are doing now. - Thanks Stephen, I'm just planning to do as you suggested.
