Perf Tune is not an simple Question !!!!
its a process !!!
Performance of Informatica is dependant on the performance
of its several components like database, network,
transformations, mappings, sessions etc. To tune the
performance of Informatica, we have to identify the
bottleneck first. Bottleneck may be present in source,
target, transformations, mapping, session, database or
network.
Identify bottleneck in Source
Identify bottleneck in Target
Identify bottleneck in Transformation
Identify bottleneck in sessions
DATABASE OPTIMISATION
OPTIMUM CACHE SIZE IN LOOKUPS
so and so,,,,,,,,,,,,,,,,
