Tessabyte vs iPerf Falcon

Experience the difference with Tessabyte — a powerful tool for measuring and analyzing network performance. This utility sends TCP and UDP data streams across your network and computes important metrics such as upstream and downstream throughput, packet loss, jitter, and round-trip time, and displays the results in both numeric and chart formats. Whether you're troubleshooting connectivity issues, validating upgrades, or optimizing your network, Tessabyte provides precise insights into its speed and reliability. Tessabyte uses a client-server setup to run tests, so a server component (which can be downloaded at https://www.netmantics.com) is highly recommended for local network testing. However, the application also offers access to public test servers. What can you do with Tessabyte? • Wi-Fi Speed Tests: Test wireless networks for throughput and reliability. • Network Capacity Tests: Assess the maximum data transfer rate that a network link can support. • Link Quality Analysis: Determine the quality of individual network links. • Stress Tests: Simulate high traffic loads and observe how the network behaves under congestion. • Quality of Service (QoS) Assessment: Evaluate how different traffic types are prioritized in the network. • Firmware and Hardware Updates Validation: Verify the impact of network device firmware or hardware upgrades. • LAN Bandwidth Tests: Don't take your local network speed for granted. Test, verify, and monitor. • Network Topology Planning: Understand how network design choices impact performance. • Comparative Benchmarking: Compare the performance of different network components or analyze how your network behaves at various times of the day. • Security Assessment: Evaluate the impact of security measures on network performance. • Load Balancing Verification: Test the effectiveness of load balancing in a network. • SLA Compliance Verification: Ensure that the network meets its Service Level Agreements. Why Tessabyte: • Accurate, real-time measurements • Reports in PDF and CSV formats • Customizable TCP and UDP traffic parameters • Support for both IPv4 and IPv6 • Cross-platform compatibility: an iOS/iPadOS client can "talk" to a macOS or Windows server, etc.

iPerf Falcon brings native iPerf testing to iPhone, iPad, and Mac. Measure Wi-Fi, LAN, routers, NAS devices, servers, or broadband to find network bottlenecks. Connect to your chosen endpoint, listen locally, or automate the test over SSH. You control the target and method. Three ways to get started Connect • Enter any iPerf host and port, or choose from 8 free public servers • Check port reachability with one tap; Falcon Pro can also save and pin frequent targets Listen • Turn your iPhone, iPad, or Mac into an iPerf server • Listen on all interfaces or choose an IPv4 address from Wi-Fi, Ethernet, cellular, or VPN • See exactly which address and port the other device should use • Start once and accept multiple client connections until you stop listening; results follow your automatic or manual saving preference SSH (Falcon Pro) • Connect to OpenWrt, Linux, or another SSH device; start the iPerf server, run the test, and clean up automatically • Authenticate with a password, an OpenSSH private key, or no credential on a lab device configured to allow it • Run the server remotely, or listen locally and have the SSH endpoint connect back Professional measurement without the friction • Both iPerf3 and iPerf2 engines, switchable in one place • TCP and UDP with upload and download modes; iPerf3 also supports simultaneous bidirectional tests • A graphical form for direction, protocol, duration, parallel streams, bitrate, and more • Chart-focused results with clear live and average speeds, minimums and peaks, test stages, and elapsed measurement time • Throughput charts label direction, time, and units, follow your bits/s or bytes/s preference, and let you tap to inspect each sample • Open current test details during or after a run to see the connection and full configuration • Separate upload and download speeds, charts, and metrics for bidirectional tests • Live Ping, TCP RTT, retransmissions, UDP jitter, and packet loss • Text details for each measurement interval, plus a searchable parameter and command reference Keep the results that matter • Save every run automatically, or keep only the tests you choose • Add notes, search instantly, and load a saved configuration for your next test • History details share the test screen's readings and layouts, with direction, measured time, averages, extrema, protocol metrics, charts, interval text, and saved parameters and commands • Export individual results as CSV or JSON, or create a shareable result card Falcon Pro One purchase unlocks these features on iPhone, iPad, and Mac: • SSH remote orchestration • Advanced graphical options and iPerf command-line configuration—paste a command to parse and synchronize the graphical form, then save complete commands for quick reuse • Five built-in scenarios for VoIP, 4K streaming, gaming, NAS backup, and Wi-Fi roaming, plus custom presets • Saved targets and SSH endpoints • Charts and metric comparisons for up to 6 runs, plus batch history export Designed for Apple devices On iPhone, landscape keeps readings and run controls visible while charts and details scroll independently. Wide iPad and Mac windows show parameters and results together. On iPhone Duo, layouts adapt to both displays and place content on either side of the fold when space allows, preserving your page, drafts, and current test state. Larger text, light and dark appearances, and nine languages are supported: Simplified Chinese, Traditional Chinese, English, Japanese, Korean, German, French, Spanish, and Russian. On iOS 27 and macOS 27, App Shortcuts can open Speed Test, History, or Settings, or load a saved preset. Privacy first No account is required, and there are no ads or analytics trackers. Test history stays on your device. SSH passwords and private keys are stored only in the system Keychain. Test traffic goes only to the target you choose; the target list briefly checks port reachability.
