Python is taking more cpu for initiating execution

anjo john

We have cross compiled python version 2.7.3 and integrated with ipnc sdk. our aim is to transfer the files to AWS server using s3cmd which runs on python.

The problem we are facing is while starting the execution of any command related to python its taking 15-20 sec time and around 40-50% cpu usage.

for example i just run "s3cmd --version" it will execute successfully but initially it will take time and cpu usage before showing the version. We verified by the sample python script , the same issue we face there.

has anyone faced this kind of issue before? from system its working fine.

Little help will be appreciated.

Thanks,

Hi Anjo,

Could you check what is the time for executing python commands with some other (newer) python version?
Are you add all available patches to your python?
What cross-compiler you are using?

I followed this link for cross compiling python and tried all the python version listed in the link. i am using arm-arago-linux-gnueabi which is in ipnc_rdk. I am not able to compile the latest python version 3.5 , no information for this is not available. i Have checked up to version 3.2.2. Even for this the time taken for starting simple scripts is 10~15 seconds.
