I have a network mapped drive that sometimes is very slow, as it is not always slow would be difficult to figure out the problem, I am wondering what would be the reason.

Some other people are using it and it's slow on every single computer.

I am using a My Book Live Duo, once I restart it, it's much faster.

I checked the system it shows following messages,

  • The network link is down or has become intermittent. Please check your network connection.

  • Drive failed in location B

I use the following:

  • Linux Debian
  • MyBook Live Duo
  • All operating are systems Windows 7

The network mode is static on MyBook Live Duo

It is too complicated to describe everything but this is what the Windows Performance Monitor stuff is for.

On a Windows server, set up a performance monitor window with all the things that could possibly be relevant such as network traffic, errors, disk traffic, CPU usage, etc. Also check your event logs for interesting things happening when it is slow such as backups, shadow volume copies, RAID controller errors, SMART errors, or who knows what.

On a Linux server, I recommend logging into the command line using SSH, then using vmstat 1 or iostat -x -k /dev/sd[a-z] 1 to view disk usage. atop is another good tool. Use less /var/log/syslog or less /var/log/messages to see the system log. dmesg is a fast way to see the kernel log for RAID or disk errors. netstat -s will show network traffic stats including errors. watch -d 'netstat -s' is quite handy.

Edited to add: Do this on the server. – Zan Lynx Feb 4 '13 at 23:47

I used vmstat1 but it shows the commend is not found and used less /var/log/messages but it should permission is denied although I logged in using admin credentials – Jack Moore Feb 5 '13 at 0:20
