RFH: slow awk scripts wanted
Hi,
I am new to awk but quite like it, and I am considering working on
some changes to mawk that would have an impact on performance.
Problem: generally awk is already more than fast enough for me. So
chances are, this would end up ruining it for everyone else! Unless
you help.
If you have
- a (fast or slow) awk script you use regularly on large sets of data
- a scripts you wrote naïvely and then had to revise to make perform
acceptably (the before and after would be great)
- an awk script you use very often
- a shell script in which awk is run in the inner loop
- a long stream of data you regularly use awk to digest
then I would like to know about it so I can run some tests. In other
words, I am looking for performance bugs and performance success
reports.
As active Debian users, you are the target audience. Dedicated awk
users in awk-specific forums might have adapted their behavior to
existing implementations, producing skewed results; plus, their
scripts are already nicely archived.
Please respond privately and I will send a summary in a week or so.
If your script is of general interest, I encourage you to contribute
to a relevant thread on comp.lang.awk or a site like awk.info and
point me there instead.
If you think I’m crazy, feel free to let me know that, too.
Looking forward to your thoughts,
Jonathan
