 Hi team,

 I am experiencing some significant performance regression when I upgrade
 from 6.0 to 6.1 (and 6.1.1). Page load time roughly triples across the
 site.

 I do not have a profiler running but using Query Monitor I can see a
 significant increases in object cache hits (14k to 110k). I understand
 this is partially expected due to the caching improvements.

 I am running a fairly large (170k posts) site with Woocommerce and a
 number of plugins.

 I am happy to provide more detailed analysis but not sure what is the best
 profiling tool or method to understand where the regression is coming
 from. If you can provide some guidance I will try to collect more data.

 Thanks,
 Jason
