iPerf Tools vs iPerf3 Client & Server

iPerf features * Use the up to date iPerf3 library (3.13) * TCP and SCTP Measure bandwidth Report MSS/MTU size and observed read sizes. Support for TCP window size via socket buffers. * UDP Client can create UDP streams of specified bandwidth. Measure packet loss Measure delay jitter Multicast capable * Cross-platform: Windows, Linux, Android, MacOS X, FreeBSD, OpenBSD, NetBSD, VxWorks, Solaris,... * Client and server can have multiple simultaneous connections. * Server handles multiple connections, rather than quitting after a single test. * Can run for specified time. * Print periodic, intermediate bandwidth, jitter, and loss reports. * A server accepts a single client simultaneously (iPerf3). Support information If there is any issues or feedback, please don't hesitate to contact support@xnano.net

Requires access to an iPerf3 server (local, VPN, or remote). This is not a general Internet speed test. iPerf3 Client & Server brings the standard iPerf3 tool to iPhone and iPad with a clean, native UI. One purchase also unlocks the Mac version. Measure real throughput across Wi-Fi, cellular, VPN, or LAN. Compare routers and access points, validate ISP or VPN changes, and find bottlenecks. Key features: - Client and server modes - TCP/UDP tests, including bidirectional and reverse - Advanced controls: duration, parallel streams, bandwidth caps, window size, MTU - Shortcuts automation + x-callback-url for power users - Saved server profiles and favorites - History with charts and CSV/JSON export - Detailed metrics: throughput, latency, jitter, packet loss Automate repeatable workflows with Apple Shortcuts or x-callback-url (run tests, fetch results, and chain actions). Built for network engineers, sysadmins, and power users who need accurate, repeatable results.
