performance issue

We have upgraded our HP UX from 10.10 to 10.20 and we are running IDS 7.12 for our production machine and ... our machine performance is getting poor any body would suggest correction ? thank you very much --garnadi below is our onconfig file #************************************************************************** # # INFORMIX SOFTWARE, INC. # # Title: onconfig.std # Description: INFORMIX-OnLine Configuration Parameters # #************************************************************************** # Root Dbspace Configuration ROOTNAME rootdbs # Root dbspace name ROOTPATH /dev/vg02/rlvol1 # Path for device containing root dbspace ROOTOFFSET 0 # Offset of root dbspace into device (Kbytes) ROOTSIZE 2000000 # Size of root dbspace (Kbytes) # Disk Mirroring Configuration Parameters MIRROR 0 # Mirroring flag (Yes = 1, No = 0) MIRRORPATH # Path for device containing mirrored root MIRROROFFSET 0 # Offset into mirrored device (Kbytes) # Physical Log Configuration PHYSDBS rootdbs # Location (dbspace) of physical log PHYSFILE 90000 # Physical log file size (Kbytes) # Logical Log Configuration LOGFILES 10 # Number of logical log files LOGSIZE 65000 # Logical log size (Kbytes) # Diagnostics MSGPATH /appl/informix_712/online.log # System message log file path CONSOLE /dev/console # System console message path ALARMPROGRAM # Alarm program path # System Archive Tape Device TAPEDEV /dev/rmt/0m # Tape device path TAPEBLK 20 # Tape block size (Kbytes) TAPESIZE 2000000 # Maximum amount of data to put on tape (Kbytes) # Log Archive Tape Device LTAPEDEV /dev/rmt/0m # Log tape device path LTAPEBLK 20 # Log tape block size (Kbytes) LTAPESIZE 2000000 # Max amount of data to put on log tape (Kbytes) # Optical STAGEBLOB # INFORMIX-OnLine/Optical staging area # System Configuration SERVERNUM 0 # Unique id corresponding to a OnLineinstance DBSERVERNAME dbkpei # Name of default database server DBSERVERALIASES # List of alternate dbservernames DEADLOCK_TIMEOUT 60 # Max time to wait of lock in distributed env.
