10 Gigabit Ethernet from the Network: pop-up menu.Įnter the desired number of test runs into the provided field. Alternatively, select File > Choose Test Volume. In the LanTest “Test settings” section, choose your harddisk to be tested by clicking somewhere into the Volume: line. Right-click on the LanTest program icon and select Open.Note for LanTest macOS beta versions: If an error message is issued when opening LanTest (“HELIOS LanTest can't be opened because it is from an unidentified developer.”) do the following: Login, select the “HELIOS Tools” sharepoint and navigate to “HELIOS LanTest > for Mac OS X (10.6 and higher)” or “for Windows” and select Download from the “Transfer” menu. HELIOS LanTest can be downloaded via HELIOS WebShare at: Windows note: supported file server protocols – SMBĪll performance testing has been done against SMB volumes.
Even so, HELIOS LanTest has also received limited testing using NFS and SMB. At present, other Mac protocols, including NFS and SMB, only offer a fraction of the performance and have limited compatibility (no support for Aliases, Time Machine backups, Spotlight searches, server fast file find), as well as permission incompatibilities. MacOS note: supported file server protocols – AFP, NFS, SMBĪll volume performance testing has been done against AFP volumes as AFP 3.x offers the best performance and is most compatible with Mac clients. It measures the random access time to a connected storage. Therefore, HELIOS LanTest has a disk latency testing (called “Seek test”) functionality to present the end-to-end latency in milliseconds. SAS, Fibre Channel, iSCSI), and finally the physical disk seek and read operation. Today’s server storage access for clients can be very complex: it includes client network connection, file server caching, raid controller caching, various RAID configurations, connected disks (e.g. It also recognizes how many LanTest users are concurrently running performance tests, and therefore allows determining the server performance under multi-user load. HELIOS LanTest displays the results on the screen (see figure above) and collects them in a logfile for later use, e.g. Make sure to select the proper network environment for the existing connection between client and server: Five different setups are available, to range from slower networks like standard Ethernet/DSL, up to 40 Gigabit Ethernet. This version has been designed using the latest native APIs for testing common file I/O operations, which are used when working with files on server volumes. It is very easy to use within seconds and scales from single local disk testing, to testing performance of a network volume, as well as multi-user concurrent client testing against a single server volume. HELIOS LanTest is a very popular network performance and reliability testing solution for Mac and Windows clients.
