Clearly the development server is hardware wise way below the specs of the Dell but software wise they are identical (they get upgraded at the same time).
As a first step, you have to test subsystems one by one.
Try this to see how fast the CPU and kernel are (including meltdown/spectre slowdowns): time dd 2>/dev/null if=/dev/zero of=/dev/null bs=1 count=1000000 Then try this to see how fast your disks are for DB operations: cd /a/directory/on/the/filesystem/you/want/to/test time bash -c "for((i=0;i<1000;i++)); do dd 2>/dev/null if=/dev/zero of=test bs=1 count=1 conv=fsync;done" rm test Regards. -- Roberto Ragusa mail at robertoragusa.it _______________________________________________ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
