Network latency -- how long does it take for a packet to travel …
If latency is a problem, think about a content delivery network, which serves each continent on the continent. That might help if You don't need data written to Your NY server in realtime. Cisco has some tiny bits for VOIP, but worthwile to read, there is …
Why do mobile networks have high latencies? How can they be …
Core network latency: Carrier dependent cost for transporting the packet from the radio tower to the packet gateway: in practice, 30–100 ms. Internet routing latency: Variable latency cost between the carrier’s packet gateway and the destination address on the public Internet.
performance - Are networks now faster than disks? - Server Fault
Feb 22, 2011 · cache memory > memory > disk > network. With each step being 5-10 times the previous step (e.g. cache memory is 10 times faster than main memory). Now, it seems that gigabit ethernet has latency less than local disk. So, maybe operations to read out of a large remote in-memory DB are faster than local disk reads.
How much network latency is "typical" for east - Server Fault
West coast to east coast: 215 ms latency, 46 ms transfer time, 261 ms total. West coast to west coast: 114 ms latency, 41 ms transfer time, 155 ms total. It makes sense that Corvallis, OR is geographically closer to my location in Berkeley, CA so I expect the connection to be a bit faster.. but I'm seeing an increase in latency of +100ms when I ...
What tools are available on Windows to simulate/emulate network …
45. I am looking for tools for Windows that can act as a reverse-proxy in front of a server to introduce various networking issues like jitter, delays, or packet loss. My preference is a software solution that will work on Windows. Httpd mod_proxy doesn't appear to support such a configuration, and googling for a tool in this category is ...
What is the minimum gigabit Ethernet latency I can expect?
Sep 18, 2017 · As @barbequesauce has pointed out, twisted pair requires some complex encoding, so 1000BASE-T NICs will require at least 10 µs per side for the codecs (plus system bus and IRQ latency). Twisted-pair cat.6 has a velocity factor of 65% (~200,000 km/s), so it adds .05 µs or 50 ns per 10 m. Fiber isn't really faster (VF of 67%) but uses simpler ...
networking - Network latency: 100Mbit vs. 1Gbit - Server Fault
Moving all internal traffic to an internal network will reduce collisions and total packet counts on the outgoing NIC and provide larger gains than the .04ms latency gain of a single packet. Reduce the number of requests per page to reduce page load latency.
What is the best way to measure latency via a "telnet to port" test ...
I'm writing a Graphite/Diamond collector measuring network latency. Specifically it should measure the time it takes to open up a connection to a port on a remote server. And it needs to work via script, i.e. no humans on the keyboard running this interactively.
How can I control the network latency? - Server Fault
Jun 10, 2009 · 2. Basically, you need a switch/bridge/router, which slows down your traffic. I would strongly recommend to not use a tool on client or server, but between them on your network equipment. Namely, you need a WAN emulator. These pieces of software let you configure bandwidth, delay/latency and random packet loss.
How does geography affect network latency? - Server Fault
3. The number of hops between point A and point B will introduce latency. Count the number of hops since this is your best indicator. A few words of caution. Methods for evaluating the network path are not consistent with how the actual packet will flow. ICMP may be routed and given a difference QoS.
