Performance tune

Hi team, I'am facing problems with system performance:

My enviorment is:

->Cluster with Intel Xeon 2.80Ghz

->5,50GB RAM

Running Windows Server 2003, and SQL 2005, with ECC5

The Hitratio is fine with values between 93% and 99%, but in the program buffer i´am facing some problems:

The program buffer as 512.000KB alocated , but in 5 hours of activity the free space changes to 1.092Kb with 0,22% , and

the swaps start do grow to 15.0000, the free directory as 115.352 entries / 90,12%

I also get swaps to in the buffer initial records, and in generic key.

In transaction RZ20 the system has the following Alerts:

21.04.2010 11:33:50 PRD SAP_PRD_00 Program Swap ACTIVE 113,300000 /min > 100,000000 /min (15 Min.) SAP buffer swap exceeds threshold

21.04.2010 10:48:50 PRD SAP_PRD_00 Program Swap ACTIVE 207,800000 /min > 100,000000 /min (15 Min.) SAP buffer swap exceeds threshold

21.04.2010 10:33:50 PRD SAP_PRD_00 Program Swap ACTIVE 82,100000 /min > 50,000000 /min (15 Min.) SAP buffer swap exceeds threshold

21.04.2010 09:48:50 PRD SAP_PRD_00 Program SpaceUsed ACTIVE 100 % > 98 % (15 Min.) SAP buffer:buffer storage usage exceeds threshold

21.04.2010 09:18:50 PRD SAP_PRD_00 Program SpaceUsed ACTIVE 92 % > 90 % (15 Min.) SAP buffer:buffer storage usage exceeds threshold

I tried to change the program buffer to 600.000 but the sytem don´t start.

Thanks & Regards,

NG
