Steve Gill | A customer is complaining that my application is generating an excessive
amount of network traffic in comparison to other applications. Apparently users have noticed slower response times on the network. As it's not a database-intensive application I'm a little surprised. No one else has reported this problem. Any suggestions on what might be causing this? Client/Server Local Area Network DBISAM 4.25 Build 1 Delphi 7 Regards, SteveG |

I have a hard time believing that DBISAM is responsible for slowing down a modern 100Mbit or faster network all by itself. Are you performing any batch processes over a remote session connection such as a while not eof..do type of looping on a large table ? -- Tim Young Elevate Software www.elevatesoft.com |

Jason Lee | That's funny! You mean a multiuser database oriented program is actually
utilizing the network!?! ![]() I love it when customers who have crappy networks say "Well, Word & Excel don't have the problems that your program does." Then I explain that Word & Excel don't have 30 simultaneous connected users sharing the same data files over the network. > A customer is complaining that my application is generating an excessive > amount of network traffic in comparison to other applications. > Apparently users have noticed slower response times on the network.

Me too. It looks like they're using a product called Network Probe. The screenshot they sent shows 383,276 packets being sent, equaling 380.3MB. I'm not sure but it looks like it could be over almost a 5 hour period. > Are you performing any batch processes over a remote session > connection such as a while not eof..do type of looping on a large > table ? I don't believe so but I'll recheck my code. As I mentioned, no one else has reported this problem so I find it hard to believe it's the application or DBISAM. Regards, Steve |

Ha ha, yeah sometimes they just don't get it. > Yeah, people are actually *using* your program! ![]() That's a plus. ![]() Regards, Steve |

> And they're sure that the entire 380 MB is from DBISAM ? Well, they think it is. It sounds a bit high to me. I can email you the screenshot I have if you like. Regards, Steve |

Steve Gill | Hi Tim,
> Does the screen shot show that it is DBISAM by some indication ? ![]() No, not directly. It shows my application and the IP addresses. But as my application doesn't do any network communication except for a DBISAM Client/Server connection, I guess it infers it. Or perhaps my application is just complete crap. ![]() Steve |
