Slow Backup to NAS (temporarily) cured by reboot

Thread needs solution

I'm currently running True Image 2016 on a Windows 7 box.  Frequently I've noticed very slow transfer of a backup to a NAS box associated wity slow screen response.  During those times TaskManager>Networking displays a transfer rate ~.6% of a nominal maximum link speed of 1Gbps.  After a reboot the process (I have several hard drives and 7 backup programs scheduled to run at different times) the various programs run at 60% (100 times faster!!) for a while and then revert to a slow speed. 

What is causing this and what can I do to stop whatever is recurrently slowing my backup speed by 2 orders of magnitude?

Very good question and so tough to answer.  There are many resourse aspects that can and do effect network transmission performance.  I might suggest that to start you should run a backup task while at the same time having Windows Task Manager open and view your system to see what if anything you can discover.  You should look at Ethernet speed, Disk performance. and CPU utilization and take note of what occurs there throughout the transfer.  You should also view what processes and services are running and how much of what resource they are consuming. 

 

Thanks Enchantech...

Currently post re-boot network TaskManager>Network utilization is 60-75% and CPU utilization is 20-30% with no desktop response interference.  I'll take a another look when it slows.  The fact the system works fine now suggests I have it set up properly.  I'm just not sure what makes it slow by 2 orders of magnitude.

Again it is very hard to say.  Keep digging and hopefully you will find the answer.
