[otrs] sysconfig run slowly

Hi List, Recently upgrade my OTRS from 2.3.1 to 2.3.4 and I did change my box (a failure hardware). I have identical hardware and apache/perl configuration. All runs excellent except sysconfig. When I go to sysconfig to set up any item, response takes til 2 minutos. When I save the changes, response takes til 2 minutes again. Any ideas about how to to solve this issue? Thanks in advance. Karlos.
