today at work I noticed something strange. My box there has kUbuntu 7.10 (yes, I know, quite old, but does what it is supposed to do).
Now, 7 years ago, computer were smaller and slower, and I can remember that I was using awk back then for some heavy text processing. Now, the same should be possible today, just faster. Or so I thought.
Well, while awk was running, it started to consume more and more memory, after 2 million lines it basically didn't progress anymore but was only swapping all the time. I removed all unnecessary code in my script, and now I managed to run it over the complete file, but it took 20 minutes (on a 2.something GHz system with 1 GB RAM !!!)
So I set out to find another awk to see whether my GNU awk maybe has some problem.
I found awka, which is a awk-to-C compiler, but which didn't seem too alive. Then I found mawk, which is another regular awk, and compiled this one. How to put it, this one was blazingly fast, it processed the 4 million lines in 10 seconds or so :-) ! Then I added the commented code back in, and now the version, which my original GNU awk could not process at all until the end, was processed in 30 seconds by mawk.
Now to something completely different: you know KDE runs more or less everywhere, also on this evil OS from somewhere in the states, I forgot the exact name ;-)
