Unfortunately, without knowing exactly what your script does, and the environment in which it is running, it's hard to give you any concrete advice or anything but questions. If the script is performing differently, something must have changed, it's just a matter of identifying what it is. - What version of Python were you running before, and after? - Does the script rely on any third-party libraries which have been upgraded? - What operating system are you using? Is it the same version as before? You mention top, which suggests Linux or Unix. - What does your script do? If it is downloading large amounts of data from the internet, has your internet connection changed? Perhaps something is throttling the rate at which data is downloaded. - Is the amount of data being processed any different? If you've doubled the amount of data, you should expect the time taken to double. - If your script is greatly dependent on I/O from disk, a much slower disk, or heavily-fragmented disk, may cause a significant slowdown. - Is there a difference in the "nice" level or priority at which the script is running? Hopefully one of these may point you in the right direction. Would you like us to have a look at the script and see if there is something obvious that stands out? -- Steven _______________________________________________ Tutor maillist - [email protected] To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
