page faults of sagent.exe

hello, pmon.exe is saying that sagent.exe is using 10920K memory and that it had 467365338 page faults. since this means ( i think ) that he is retrieving memory pages from disk this is slowing down the server NT diagnostics shows me that we have 2GB memory ( which is correct ) and that there is 1.3GB available How can I reduce the page faults ? Can I assign more memory to sagent.exe and will this decrease the number of page faults ? Thanks for your help.
