![]() To run 15-second long bandwidth-test to the 10.0.0. Receive test maximum speed (bits per second)Ĭonnection-count ( integer 1.255 Default:) If random-data is set to yes, the payload of the bandwidth test packets will have incompressible random data stream so that links that use data compression will not distort the results (this is CPU intensive and random-data should be set to no for low speed CPUs) Transfer test maximum speed (bits per second) There is no acknowledgment required by UDP this implementation means that the closest approximation of the throughput can be seen.ĭirection ( both | receive | transmit Default: receive) To see the maximum throughput of a link, the packet size should be set for the maximum MTU allowed by the links which is usually 1500 bytes. The UDP tester sends 110% or more packets than currently reported as received on the other side of the link. Therefore this statistic is not as reliable as the UDP statistic when estimating throughput. As acknowledgments are an internal working of TCP, their size and usage of the link are not included in the throughput statistics. Statistics for throughput are calculated using the entire size of the TCP data stream. Please review the TCP protocol for details on its internal speed settings and how to analyze its behavior. The TCP test uses the standard TCP protocol with acknowledgments and follows the TCP algorithm on how many packets to send according to latency, dropped packets, and other features in the TCP algorithm. WMI doesn't seem to enumerate info about the pci ports, especially not disconnected ones.The Bandwidth Tester can be used to measure the throughput to another MikroTik router (either wired or wireless) and thereby help to discover network "bottlenecks". These properties are for the named device, and not the PCI slot on the motherboard. The integer values for the other properties aren't too hard to find by googling their driver key name, like DEVPKEY_PciDevice_MaxLinkSpeed The ExpressSpecVersion property is the PCIe version, where PCIe 1.0 = 0 and PCIe 3.0 = 2, etc. ![]() Standard NVM Express Controller 2 3 4 3 4 If you’re watching Netflix on your laptop, run the speed test on that device. ![]() Intel(R) Dual Band Wireless-AC 8 2 1 1 1 1ĪSMedia USB 3.1 eXtensible Host 2 3 2 3 2 Assuming that you are getting the speeds you’re paying for (see above paragraph), here are 4 tools to determine if you’re the lucky beneficiary of ISP throttling: For control purposes run a speed test on your device. ![]() High Definition Audio Controller 2 4 16 3 16 ![]() It shows a table like this on my PC: Name ExpressSpecVersion MaxLinkSpeed MaxLinkWidth CurrentLinkSpeed CurrentLinkWidth MaxLinkWidth =$_.GetDeviceProperties('DEVPKEY_PciDevice_MaxLinkWidth' ).deviceProperties.dataĬurrentLinkSpeed =$_.GetDeviceProperties('DEVPKEY_PciDevice_CurrentLinkSpeed' ).deviceProperties.dataĬurrentLinkWidth =$_.GetDeviceProperties('DEVPKEY_PciDevice_CurrentLinkWidth' ).deviceProperties.data MaxLinkSpeed =$_.GetDeviceProperties('DEVPKEY_PciDevice_MaxLinkSpeed' ).deviceProperties.data # request connection properties from = $_.NameĮxpressSpecVersion=$_.GetDeviceProperties('DEVPKEY_PciDevice_ExpressSpecVersion').deviceProperties.data $pciStats = (Get-WMIObject Win32_Bus -Filter 'DeviceID like "PCI%"').GetRelated('Win32_PnPEntity') | This method uses the WMI Bus PnP device driver properties # Get all devices related to PCI BUS ![]()
