Looks like code using strstr() and libc-2.27 is running 4 times slower than was with libc-2.23. Having a look at profiled code executed in various moments show different versions of strstr :

- libc-2.27.so: strstr.c, str-two-way.h - this is current version ubuntu 18.04.1

Same code, profiled March 13, 2018 :

- libc-2.23.so: strstr-sse2-unaligned.S

Is the removal of sse2 optimized code from strstr() an error of some kind ?
