It is. Actually what you’ve done (stay very long on a very old version is not 
such a good idea ;) (will make the upgrade a lot more complex).

Since you’re using a very old version you may want to export your data, install

Re performance you can get good perf in 4.2 too. If I had to guess I’d say 
you’re missing indexes in the DB, see


PS: Since this is a complex operation, I’d highly suggest that you hire some 
xwiki experts. There are companies offering such expertise and that are 
sponsoring the development of the xwiki project. See
