We are making use of kettle job for the following task:

We take dumps from databases which generates .csv files and then we zip them using batch files. all the movements of files, zipping is done through command scripting, kettle is only used for passing arguments to these scripts. but still whenever this kettle script is run, cpu usage shoots up very high to 80% of total cpu usage. due to this our other utilities stops responding.

attached are the debug level circle_job.loglogs of our utilitiy

Some useful facts about the server on which kettle job is running:
a) OS: Windows XP
b) RAM: 4gb
c) processor: xenon 3.0Ghz dual core processor

kindly guide us to resolve this issue.
any help would be appreciated
