I asked some technical guy in parallel via email and got this answer, which is very interesting for me - and so it is rather clear that is not very good to use Enterprise Kernel for a machine with e.g. 1 GB RAM:
"Due to PAE (HIGHMEM64) and 4GB split, performance penalty can be as large as 10-30%. Thus if for the machines with less than 4GB it is best to use SMP or UP(in case of 1 CPU)."
