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.
