Hey,  I've downloaded the pdf about using large pages and did everything like in the instruction, but my log shows me weird things.
My question is:  is it enabled or not?   Here the log ->

Large pages are not being used.
What's your operating system?
Parent - By tacticalskiller (*) [de] Date 2012-01-20 15:41
Windows 7 Ultimate 64x
Parent - - By tacticalskiller (*) [de] Date 2012-01-20 15:41
So what can i do?

what ram do you have.  looks like maybe you don't have any free.

For Windows 7 Ultimate it's relatively easy. Just follow the instructions in the pdf attached to this post: http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?pid=251423#pid251423 to enable "lock pages in memory".
