Really?! Commenting out this (use srfi-1) does not make a difference there? Strange! I just double-checked with chicken rev 022dce82 (master built yesterday). (Before I used rev 274e7afa.) Additionally I tried now chicken 4.10.1 built from the tarball distributed from call-cc.org. (I moved the installed version out of the way for this test.) All the same result: slowdown of roughly 4x (160:40). OS: Debian stretch, ARMv7 Processor rev 10 Another try: Raspberry Pi, Raspberian. Similar results, about 60:20 >> I have used CHICKEN Version 4.10.1 (rev f36c19c) and compiled with >> default options. Used default option this time.

An ARM-related problem? _______________________________________________ Chicken-users mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/chicken-users
