I did not know that information, although it does not apply to my case (I work with domains with a limit of 63 compatible IDN characters). I worked in the past with 'parallel' and it consumes too much and it is not as fast as xargs (you can always make a sort -u). Additionally I replaced 'curl' with 'host', since I'm only interested in verifying if the domain exists ('curl + http_code' work with HTTP (S) or FTP (s) and if the domain is active on another port, curl doesn't detects, therefore they are inefficient for my purposes). Thank you for your contribution.
