WIFIPERF MACOS FOR MAC OS
Client and server can have multiple simultaneous connections (-P option). A Technical Site Providing Uninstall Tutorial For Mac OS X.Cross-platform: Windows, Linux, Android, MacOS X, FreeBSD, OpenBSD, NetBSD, VxWorks, Solaris.Client can create UDP streams of specified bandwidth.Support for TCP window size via socket buffers.Report MSS/MTU size and observed read sizes.It is released under a three-clause BSD license. iPerf3 is principally developed by ESnet / Lawrence Berkeley National Laboratory. iPerf was orginally developed by NLANR/DAST.
WIFIPERF MACOS CODE
This is a new implementation that shares no code with the original iPerf and also is not backwards compatible. For each test it reports the bandwidth, loss, and other parameters. It supports tuning of various parameters related to timing, buffers and protocols (TCP, UDP, SCTP with IPv4 and IPv6). I don’t know if the new operating system and router firmware are responsible for this reduction in throughput.IPerf3 is a tool for active measurements of the maximum achievable bandwidth on IP networks. Fortunately, the 802.11ac Time Capsule delivered excellent performance just about everywhere else in my house (see the illustration of my home’s floor plan for details). I repeated these tests several times to ensure I wasn’t seeing an anomaly, but the results were consistent. (If you’re wondering why the numbers for the home office are higher than they are for the home theater, despite the longer distance, it’s because the home theater is double-walled and double-insulated to enhance its acoustic properties.) Since router performance can be greatly influenced by atmospheric and environmental conditions, I always run fresh benchmarks for each router comparison I conduct, ideally testing all routers I’m going to write about on the same day (after updating the router’s firmware and the OS on the client and server).Ĭuriously, the Time Capsule’s 802.11ac performance was much lower at long range that what it was before the updates.Ĭuriously, I measured much lower TCP throughput this time when the client was in my home theater (35 feet from the router) and in my home office (65 feet from the router): 73.7 mbps now, compared to 100 mbps then for the home theater and 53 mbps now, compared to 167.8 mbps then, for the home office. Since I compared the AirPort Extreme to an Asus RT-N66U 802.11n router in that story, I decided to compare the 802.11ac Time Capsule’s performance to an Asus RT-AC66U 802.11ac router this time (neither Asus model has an internal hard drive). Copying a single 10GB file across the network requires much less time, thanks to the OS X and Time Capsule firmware updates.Īs I reported in my earlier review of Apple’sĨ02.11n AirPort Extreme, some non-Apple routers deliver better performance than Apple’s products, but they lack the Apple-specific features that make Apple’s routers so easy to use-at least with Macs. Copying that file back to the iMac took place at 551.4 mbps, compared to 163.5 mbps before the updates. An operation that previously required more than 10 minutes could now be finished in less than five. The speed at which I could copy a single 10GB file from the iMac to the MacBook Air jumped by an even bigger margin: from 134 mbps to 482.1 mbps. The speed at which those files were read over the wireless network (that is, copied back to the iMac from the MacBook Air) also more than doubled, from 132.1 mbps to 309.1 mbps.
WIFIPERF MACOS SOFTWARE
With the new software and firmware, the same task required slightly less than nine minutes because the file transfer occurred at 164.3 mbps. The new software/firmware cut the time required to transfer a 10GB collection of files across the wireless network by more than half.
