Current user problem

Hi

Now a chcange my webhosting provider. He use freeBSD (till now eGW gone on Debian).
I'm was happy, finally I can use modul Current User.

But I have problem. When I activate it, then it slow down eGW.
E.g. a click to Calendar:
with Current User it takes 13.67
without Current User it takes 0.93

I use snapshot from today.

Please help where I find the problem.
