[bug-gawk] Is the speed of array index checking same as string comparison?

[Peng Yu]

Hi,

In the following example, it shows that the performance of array index
checking is same as string comparison. Is this conclusion always true?
Thanks.

$ time awk ' BEGIN {d["NA"]=1; for(i=1;i<=100000000;++i) ("NA" in d) }'

real    0m7.259s
user    0m7.024s
sys    0m0.070s
$ time awk ' BEGIN {x="NA"; for(i=1;i<=100000000;++i) x=="NA" }'

real    0m7.214s
user    0m6.970s
sys    0m0.066s
