We are a small business with 22 client machines, running Mas90 version 4.0 on a Windows server. For years we have been using a DLink unmanaged switch with 24 100mbit ports, and 2 gigabit ports.

We decided to upgrade our entire office to gigabit, so we've run all new cabling, swapped out all small switches for gigabit ones, and finally swapped our large Dlink switch for a Cisco Small Business SR2024 24-port unmanaged gigabit switch.

Before changing the last 24-port switch, the network speed, and speed of MAS90, was either the same or faster for most clients. When we changed over to the Cisco switch, we noticed a significant decrease in the speed of MAS90.

Many of the modules take 9-10 seconds to open, and people describe it as being generally sluggish. However, our network speed otherwise (for file sharing) appears to be faster than before, so the problem seems to be specific to MAS90 when hooked up to this particular switch.

Not everyone has a gigabit adapter on their computers, so some people are still running at 100mbit.

Frankly, I'm not sure what to investigate, because it doesn't appear that the switch is broken in any way, so I can't really return it, and it's an unmanaged switch, so there's nothing I can change with it.

Any insight you could offer would be extremely helpful.

Thanks!
