Actually, I think I like my comment enough to post it as an answer! When you push, git creates a pack of all the necessary objects and uploads that to the remote. This means we’re looking for a way to predict that pack size. Since the packs are compressed, that makes it very difficult to … Read more
Try using the System.Net.NetworkInformation classes. In particular, System.Net.NetworkInformation.IPv4InterfaceStatistics ought to have some information along the lines of what you’re looking for. Specifically, you can check the bytesReceived property, wait a given interval, and then check the bytesReceived property again to get an idea of how many bytes/second your connection is processing. To get a good … Read more
Water Analogy: Latency is the amount of time it takes to travel through the tube. Bandwidth is how wide the tube is. The rate of water flow is the Throughput Vehicle Analogy: Vehicle travel time from source to destination is latency. Types of Roadways are bandwidth. Number of Vehicles traveling is throughput.
Draw a picture of your request/response cycle for the application and isolate the bottleneck. You are correct that a single proxy distributing load to many application servers will require the aggregate bandwidth of all application servers. The classical solution is RR DNS. Google, Yahoo and Amazon all use this technique with a short TTL. I … Read more
No. If your unmanaged switches are so simple that they don’t do Spanning Tree Protocol (STP), connecting the second cable between them would cause a bridging loop, instantly saturating your network, making your network unusable until you remove the second cable. If they do do STP, then only one of the switch-to-switch links will be … Read more
I just got done moving our public facing servers to Rackspace Cloud Servers. About a year ago I did what you’re thinking about doing because I wanted complete control over my servers, and am a little bit sour on leasing cheap servers (the typical $100 / month “server” that’s just a PC). I finally gave … Read more
So, the problem here turned out to be a hardware issue. Things were working fine a month ago, and one does not expect failed hardware to still “work” in a degraded mode, but that’s what was happening. The troubleshooting step that revealed the issue was to actually look at the ethernet port lights on the … Read more
iftop does for network usage what top(1) does for CPU usage — http://www.ex-parrot.com/~pdw/iftop/ I don’t know how “standard” iftop is, but I was able to install it with yum install iftop on Fedora.
If you want to be sure, you can use traceroute 1.2.3.4. This will list all the routers between the host running the command and the device with 1.2.3.4 IP address.
