Disk Space
The only output files created by the license servers are the debug and report log files. The report
log files are used to generate accurate usage reports by SAMreport. If you have a lot of license
activity, these log files grow very large. You need to consider where to put these files and how
often to rotate and archive them. The license administrator has the option to suppress log file
output if disk space is at a premium.
It is recommended that the log files are local files on the server machine(s) to avoid networking
dependencies.

Memory
The FLEXnet license server uses little memory. On SunOS, lmgrd uses approximately2 MB
and the vendor daemons use approximately 2 MB each, although memory usage increases in
the vendor daemon with the size of the license file, size of the options file, and the number of
concurrent users.
Network Bandwidth
FLEXnet Licensing sends relatively small amounts of data across the network. Each
transaction, such as a checkout or checkin, is typically satisfied with less than 1 KB of data
transferred. This means that FLEXnet Licensing can be effectively run over slow networks
(such as dial-up SLIP lines) for small numbers of clients.
For a large number of FLEXenabled applications (hundreds), each of which exchange heartbeat
messages with the vendor daemon, the network bandwidth used may start to become
significant. In this case, run the FLEXenabled application and server on the same local area
network, which may require splitting licenses between two files for two servers. Users can use
a license-file list in the
LM_LICENSE_FILE environment variable to have effective access to
both servers.

Remote Mounted Disks
Macrovision recommends that you do not use remote mounted disks when you run the license
server. In other words, it is recommended that
lmgrd, the vendor daemons, the license file, and
the debug and report log files are all on locally mounted disks. If any of these files is on a remote
