There are a number of limitations to be aware of if using a Free LoadMaster:

  • 20Mbits L7 throughput
  • 50 Transactions Per Second (TPS) 2K SSL keys
Note: Statistics will be sent to Progress Kemp indicating the current peak traffic levels. If the traffic levels are approaching the license levels, a message will be displayed on the Web User Interface (WUI).
  • A maximum of two FQDNs can be created in the Global Balancing section. There is a limit of 100 UDP Queries Per Second (QPS) per FQDN for IPv4 and 100 UDP QPS for IPv6. These limits are exclusive to IP version, so it is possible to have a maximum of 200 IPv4 and IPv6 requests together. TCP connections are not limited.
  • No firmware updates can be performed on the Free LoadMaster after receiving the initial firmware release
  • Only community forum support is provided by default - LoadMaster Support and Learning Hub. However, there is an option to purchase support.
  • High Availability (HA) is unavailable
  • If the LoadMaster cannot contact the Progress Kemp licensing service at all in a period of 30 days, the LoadMaster stops load balancing, that is, the Virtual Services are stopped. In this case, it is possible to download the LoadMaster configuration by taking a backup (System Configuration > System Administration > Backup/Restore > Create Backup File). It is also be possible to upgrade the LoadMaster license to a permanent license using the Upgrade option on the Home page of the LoadMaster WUI. After a permanent license has been purchased, you can apply this to the LoadMaster using the System Configuration > System Administration > License Management option.
