It's possible.  There are some known issues with regexps and utf8,
although that should be largely mitigated by setting the
MINIVEND_DISABLE_UTF8 environment variable it is still possible that
you'd be seeing some slowdown from this.  I would recommend trying it
with 5.8.9 just to eliminate that as a possibility.
