Adding a limit does not improve processing time

[meme-lord]

If the output is limited using -max-size or -limit alterx still takes the same amount of time to finish as if no limit was applied. An optimization could be applied to exit early when the desired limit is exceeded.

For my test case I had an input file of 1000 subdomains with enrich enabled took 123 seconds.
With a limit of 350,000 set it still took ~123 seconds. With a file size limit it also took ~123 seconds.

The same happens without enrichment enabled, it always took 9 seconds with my input and permutations regardless of how low the limit was set.

Can you provide more details about how you measured the time to get results? cmd, method etc

[meme-lord]

I used a txt file with ~5000 lines of subdomains and used Alterx's built in stats for the time taken.

cat subs.txt | head -n 1000 | alterx > /dev/null
# [INF] Generated 589870 permutations in 0.4534s
cat subs.txt | head -n 5000 | alterx > /dev/null
# [INF] Generated 2915570 permutations in 18.0079s
cat subs.txt | head -n 1000 |  alterx -en > /dev/null
# [INF] Generated 7718654 permutations in 67.8527s

Use one of the worse cases for testing the limit:

cat subs.txt | head -n 1000 |  alterx -en -limit 100 > /dev/null
# [INF] Generated 100 permutations in 68.1204s
cat subs.txt | head -n 1000 |  alterx -en -max-size 1 > /dev/null
# [INF] Generated 34044 permutations in 68.4049s

I cannot reproduce this.

$ ./alterx-65a13bb -en -limit 100 < oast.subs > /dev/null

I've DMed you on Discord with the input file I'm using. Perhaps your oast.subs file isn't hitting the issues if it just consists of <sub>.site.com and not more complex patters like <a>.<b>.site.com, <a>-<b>-<c>-<d>.<e>.<f>.site.com
