linux awk seems to be more efficient with two field separators, I'll try the test on on aix 6.1 Power6 on monday

I found your AWK line time result impressive The time returned is so much shorter than what I got when using AWK during my tests. To put this difference into figures I reproduced your examples in a 64Bit AIX TL6 system. As my list has approx. 1.2 million lines runtimes are not comparable to your test easily but it may be interesting to see how the results relate to each other (from the AIX system).
The price for using AIX AWK and/or SED is definitely higher than using the LINUX equivalents. Surprisingly AIX cut seems to be faster than LINUX cut though.

unfortunately, gawk is faster on linux x86 systems, but not on ppc aix, I tried the tests on a p550 aix6.1, lpar has 1 virtual cpu, uncapped:
the script:
output:
the same test on a high performance sap-lpar, idle that time, 3 virtual cpus, uncapped, Power 6 4,7 ghz, AIX 5.3 ML09
your cut-command was very fast on all sytems, as we expected
gawk was slow in comparison to awk, the reason I think is, that gawk was compiled with gcc and not with xlc if thats possible
a gcc compiled binary can't use multiple cores I was told long time ago, don't know if that's still the case
I can find and replace text when the delimiters are unique. What I cannot do is replace text using two NON-unique delimiters:
Ex.,
"This html code <text blah >contains <garbage blah blah >. All tags must go,<text > but some must be replaced with <garbage blah blah > without erasing other... (5 Replies)
