Informix v7.12 and DEC ALPHA 2100

I've just done an upgrade on a DEC ALPHA 2100 with 2 CPUS and a GIG of memory from Informix 5.05 to 7.12 and performance is terrible!!!! I would appreciate ANY advice anyone can provide. Below I have included a copy of the onconfig file and selected system output from several time periods. #************************************************************************** # # INFORMIX SOFTWARE, INC. # # Title: onconfig.nwcoop # Description: INFORMIX-OnLine Configuration Parameters #************************************************************************** # Root Dbspace Configuration ROOTNAME rootdbs # Root dbspace nameROOTPATH /dev/online/nw_dbs_01 # Path for device containing root dbspace ROOTOFFSET 10 # Offset of root dbspace into device (Kbytes) ROOTSIZE 512502 # Size of root dbspace (Kbytes) # Disk Mirroring Configuration Parameters MIRROR 0 # Mirroring flag (Yes = 1, No = 0) MIRRORPATH # Path for device containing mirroredroot MIRROROFFSET 0 # Offset into mirrored device (Kbytes) # Physical Log Configuration PHYSDBS rootdbs # Location (dbspace) of physical log PHYSFILE 180000 # Physical log file size (Kbytes) # Logical Log Configuration LOGFILES 15 # Number of logical log files LOGSIZE 25000 # Logical log size (Kbytes) # Diagnostics MSGPATH /usr/informix7/online.log.nwcoop # System message log file path CONSOLE /dev/console # System console message path ALARMPROGRAM # Alarm program path # System Archive Tape Device TAPEDEV /online_arc/nwcoop/7level0 # Tape device path TAPEBLK 16 # Tape block size (Kbytes) TAPESIZE 99999990 # Maximum amount of data to put on tape (Kbytes) # Log Archive Tape Device LTAPEDEV /online_arc/nwcoop/7trans.log # Log tape device path LTAPEBLK 16 # Log tape block size (Kbytes) LTAPESIZE 99999990 # Max amount of data to put on log tape (Kbytes) # Optical STAGEBLOB # INFORMIX-OnLine/Optical staging area # System Configuration SERVERNUM 10 # Unique id corresponding to a OnLineinstance DBSERVERNAME nwcoop # Name of default database server DBSERVERALIASES # List of alternate dbservernames NETTYPE soctcp,1,200,CPU # Override sqlhosts nettypeparameters DEADLOCK_TIMEOUT 60 # Max time to wait of lock indistributed env.
