Re: VFP9 application in same network with email server & VOIPs
Dan Freeman
Reality manifests itself in many ways.
I'm reminded of a client who complained our software was slow. Nobody else had that complaint and this client refused to believe it could possibly be their network. No problem there!
On investigation, we discovered that the NIC in their server was throttled at 10 Mbit. Once we removed the throttle and let it operate at 100 Mbit the application started behaving properly and quickly. Their comment to us was "Wow, everything else is faster too, so what's wrong with your software "
Your case is black and white. Before VOIP, it was fast. After, it's slow. It isn't rocket science to see cause and effect.
You can, of course, use packet sniffers to determine what's using up the bandwidth but those are tools of professional hardware jockeys. Those guys are expensive. A less expensive test would be turning off VOIP for a day.
