Some reasons for a slow network data transfer and suggestions to increase your network performance


These are some reasons why your network might be running slow:

• Shortage of band-width on the network
• Instable network connection
• Limited/overloaded network equipment (switches)
• Poor system I/O speed (slow hard drives or overwhelmed file servers)
• Bad written programs that are sucking all the resources
• Antivirus / firewall / security tool that is acting as a bottle neck
• Limited memory availability on the servers and workstations involved
• Cabling issue – An old or malfunction cable can slow down your connection and affect the performance of your network and data transfer

Akso, check this common error when transferring big files from one server to another, specially if they are located remotely: “The semaphore timeout period has expired” (ERROR_SEM_TIMEOUThttp://support.microsoft.com/kb/325487

Remote storage solutions might be a good option, now that is not reserved only for larger and mid size companies due to the low cost of storage space remotely.

Here are some suggestions to improve the overall speed of your network:

1. Upgrading network equipment or limiting other applications from hogging resources
2. Looking for bad cables, bad network configurations on network equipment, and programs causing conflicts
3. Upgrading your switches
4. Upgrading your file server or moving to a faster NAS, SANS, etc.
5. Fixing or improving the Dot Net application code (if you are running one) to make it faster
6. Using of faster copy utilities such ESEUTIL as recommended by Microsoft
7. Limiting the number of Internet Explorer add-ons running on the individual workstations
