Could be related to https using the dumb protocol, but still, it's a difference too big.

For reference, the github clone was at 76dd5fe50aa8f3ed3f436ce737ab339f85e0c63e and mediawiki/core at 76881580cd9c30681aa65b228e0757c0515bbaa5 (288 commits more) when I performed these tests. _______________________________________________ Wikitech-l mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/wikitech-l
