Performance Tuning Tool
PTT identifies the matching profile for a CiscoWorks server based on the following criteria:
• The operating system for which the profile is created.
• The System Configurations like Dual CPU and 4 GB RAM.
A profile is considered matching only if it meets these criteria.
When you apply a profile, the tuned parameters, see Table 19-3 corresponding to that profile is applied
to the system.
These parameters belong to Sync Archive, Netconfig, Syslog, Device Management, Check Device
Attributes (CDA) and Inventory Collection sub systems of the RME application. The profile, with tuned
parameters when applied, improves the performance. Before running PTT, ensure that the Daemon
manager is stopped
.
Default Profile
A default profile is a profile with default values. It is used to rollback the changes done by PTT. You can roll
back the changes made to a profile, by applying the default profile. This action rolls back the parameters to
their original values. The parameters and the original values are:
Perftune - Windows and Perftune - Solaris
This profile consists of parameters that are tuned to improve performance.
