Network Performance Monitoring
For early risers it often feels like the most productive time at the office is early in the morning before everybody else arrives. There is a nice quiet calm, no distractions and no interruptions so that focus can be maintained. It even feels like the internet runs faster in the morning before everybody else gets on. In most office there is a considerable difference in computer network speed during high load and low usage times. The reason for this is that most networks are underpowered and are not doing routine performance monitoring.
Performance monitoring can help the network divert critical resources from unimportant functions to more important ones. Image a busy weekday afternoon where everybody in the office is on the network doing work. At the same time that the finance department is performing important financial transactions someone is sending a funny email video to everybody in the office. The video could be a large file which when copied to everybody in the office bogs down the network and stops the financial transactions from going through.
In this scenario intelligent network performance monitoring can assure that network will not crash and that company will not lose money. The performance monitoring can recognize that firstly there is a high volume of traffic and the bandwidth is close to being maximized. Secondly is can identify that the video is a low priority transfer and the financial transaction is a high priority transfer. Network performance monitoring can tell available network hardware, like switches, routers and front-end applications, to divert the necessary resources to complete the financial transaction before the video upload.
performance monitoring can also give good insight into the health of a network and vulnerabilities to denial of service attacks. Radware, a high quality manufacturer of performance monitoring hardware, builds hardware that not only does performance monitoring but also load balancing, and network protection.
The importance of performance monitoring can be seen in more detail here. Ariel R

Why is my internet so slow?
First up I would like to say that its normal for there to sometimes be a problem with the DSLAM F***ing up or whatever. It happened every now and then before. But in the previous weeks, it has been happening almost constantly. I have a network speed monitor in the menu bar on my iMac, and I literally can not go 5 minutes without it dropping below 50 (at best) or as low a dead 0 for long periods of time. My internet is not (supposed to be) capped, and taking an online broadband speed test I am in fact getting a lower speed (I'm on a 1500 KB/s plan, and download speeds are usually 150KB/s or so - now when I'm getting 50kb/s it's giving me a speed of 500kb/s). This leads me to believe that the problem extends past my line/distance to the tower.
I noticed that it seemed to start around when I got my new wireless router/modem combo though - it's not wireless slowdown though, as it still happens when connected via ethernet.
There is nothing else connected to the router via wireless (it is pass-protected) and I do not have a virus (I am absolutely 110% certain on this part - and no, not because I'm an up myself mac user or something :P.)
Could this be something wrong with my modem/router/line, or just a big F***up with my ISP?
No offense Ankit but is that response copy-and-pasted from the days of dialup or something? >.<

Is there a good network speed monitoring software?
I would like, on a regular basis, to test the maximum bandwidth of my internet connection. We are trying to decide whether to upgrade to a better connection to get more reliable speeds.
I am thinking of a tool that would run in the background on my PC, every X minutes, doing a network speed test (like the one from CNET or Speakeasy that check max upload and download speeds).
I have seen plenty of network monitoring software products, but those are only looking at what is actually happing, not doing regular testing of network performance. Any ideas?
Thanks.
I would like this to log the results in a file, so over time I could see how this trends, and see if maybe certain times of day the network slows down.
