Using the D-link 323 with 2 units of 1.5TB harddisks. It was working fine for 6 months, but suddenly it is slowing down alot while accessing files and working with it. This device is serving between 6 - 8 users at the same time. Hook up with a 24-ports 1GB switch and Cisco router.
There are 4 computers using 1GB network adaptors while the rest are using 100Mbps adaptors. It happens about a month ago when the files accessing is sluggish and slow. Nothing has been changed which is puzzling why this is happening.
Is there a way to monitor why the access using Excel is slow? Or software that can tell where is the bottleneck?
