Autoptimize and Smush it

Hello there i installed yesterday the plugins Autoptimize and Smush it to speed this site, on another site http://185.123.96.101/~cirugiap/testwp/wp-admin/english/ i only installed Autoptimize, now the two sites have 100% the same content, but the site where i installed Smush it doesnt seem to be as quick as this version
http://185.123.96.101/~cirugiap/testwp/wp-admin/english/
where i only installed Autoptimized, now my doubt is if the plugins work well together, could you check why this happens? I checked speed here:
