When transferring files from a LAN server to a LAN server we can achieve 100 MB/s. We can also achieve this speed when transferring from a DMZ server to a DMZ server. However, when we transfer from the LAN to the DMZ through the Sonicwall appliance, we average around 30 MB/s. We placed exclusions on the Sonicwall so that IPS and Content Filtering would not be an issue. We contacted Sonicwall and they stated that this is actually good speed. Has anyone else run into this? What speeds are you achieving? If this is normal I will stop searching but I am having a hard time believing it.
