+## Tuning LTP Performance
+
+Actual throughput of data transfer depends on the underlying network connection speed, the host's processor speed, the contact graph's data rate, the size of the bundles being sent, the round trip delay between the two hosts, and also on the LTP configuration. Check the ltprc manual page `man ltprc` for details on how to adjust LTP settings to maximize throughput. In the ION source code's root directory, there is an excel file named `ION-LTP-configuration_tool.xlsm` which may assit you in optimizing your LTP configuraiton to get the highest available throughput out of your system.
