Incredible slow performance TeraStation Pro 2 Rackmount

[grimm]

   

Hi there,

 

i am using a TeraStation Pro II rackmount with 4x250GB with RAID5. There are 3 Mobotix Network-Cameras connected to the NAS, storing their live-images on a share. The performance is so poor. When I try to connect to the share from a windows client the response is delayed up to 40sec. Opening a sequenz (JPEG-File 1,2mb) from a windows based client take the same amount of time.

Writing characteristics of the cameras are the following:

- each camera is writing its pictures in a folder-archive of apr. 100 folders with 100 subfolders in each folder. each folder contains a large JPEG-File (1,2-1,8MB) and 3 smaler files (some kB). Each camera writes a file up to 2 times a second onto the storage. I guess, this is causing performanceproblems.

Another thought was fragmentation of the diskspace causing this kind of problems. Also I disabled SMB-Log with had only a slight effect.

 

Could the device be faulty in some way?

 

Thanks for helping me out with this

If the cameras are storing as much data as it seems like that is the reason for the problems for the slow response times.  The more data present is the more data it has to sift through to load up the requested files.especially if a preview option in the Windows/OSX environment is enabled.
