Re^4: Perl threads loss of performance with system call

I do not understand what the importance of the "exact program" is, as other commands (such as echo) replicate the issue. But that said, this is the program: RNAfold from the ViennaRNA suite (https://www.tbi.univie.ac.at/RNA/).

Probably it matters. From ibidem: «Perl Bindings...The RNA module to access RNAlib C-library functions from within Perl scripts» I understand this like this: You don’t need to shell-out. You can do the stuff in pure Perl. If you fork or use threads is your design decision. Update: See here «The Crux of the Biscuit is the Apostrophe»	[reply]

I am sorry, but it is not like this. Not every single part of the framework is accessible from the Perl bindings. Ergo, the need to access it via shell-out.	[reply]

Too bad 🤪😎. Is it better in Python? As there is Inline::Python. «The Crux of the Biscuit is the Apostrophe»	[reply]
