Sharespace Extremely slow

I’ve had my sharespace for at least three years. it is set up in raid 5 and full at 20%. It is installed with the latest upgrade.

Foe the last 8 months, it has become slower and slower taking up to 3 minutes to save a 155k Word file. When I log on using the network Storage Manager, it takes forever. Usually, I end up rebooting the system and it gets better for a few days. After that, it starts again. All disk lights are flashing green very fast.

Does anyone has the same issue? Has anyone found a tool better than the NSM to try to see waht is hapenning on the system??

Let me know
