I have to say that two versions will be installed on the same VM. I create a
snapshot and install 3.1.19=about 10% CPU. And then go back to that snapshot
and compile and install 3.3.8=99%CPU....I don't know how to figure out the
cause :(

The latest.

Depends on the configuration. But the latest version can again can do more
with less CPU in most situations.

Faster request rate in the newer one?
more requests == more CPU use processing them.
Scanning the disk caches?
lots of disk I/O == lots of CPU context switching
Cache garbage collection?
lots of disk I/O == lots of CPU context switching
Those are the only known causes of traffic

Put another way: is CPU usage enough to make anyone prefer to run a version
with a few hundred known bugs and lack of several major HTTP features?
We have enough of a cross-section of users that you will get a very mixed
response there.
