Well, I have a lot of job, too; and another problem is that my mother-in-law is very ill so my wife and me have to sit beside her days and nights. > actually.. I -did- remark them out.

After the class has been created and populated - whatever you do with rows (class instances) - those evals are not executed. It could be that the functions the evals produced are slow - you've commented out all those evals and functions. That again require experimentation. And what is worse - those functions are hard to "fix" without much architectural changes. >> Perhaps those evals >> could be replaced with functools.partial >> > functools partial ? isn't this another name for decorators ? No, not at all - it is pure functional approach to a completely different problem. >>> (ps. I -do- have a large PNG of the system during a single 'page >>> impression'. It's about 7mb ..

I have never used it so I doubt I can understand the results.
