E811_TR_8.96.1.5 finetuning COK

Hi, below is the current spec. of JDE.ini of enterprise server :

Can i have the proper guide in increasing the maxNuumberOfProcesses from 30 to higher ?

[JDENET_KERNEL_DEF6]

krnlName=CALL OBJECT KERNEL

dispatchDLLName=libxmlcallobj.so

dispatchDLLFunction=XMLCallObjectDispatch

maxNumberOfProcesses=30

numberOfAutoStartProcesses=0

singleThreadedMode=Y

ThreadPoolSize=20

ThreadPoolSizeIncrement=5

Ent server OS = HP UNIX

total jde user unknown = ?

By referring to JDE.INI Tuning & Recommended JDE.INI Settings (Doc ID 654975.1)

1 COK = 6-10 users..

Therefore : 

30 x 7 = 210 ; Does it mean  30 suitable for total JDE users which is around 200 ?

If i change above kernel = def6,  do i need to change other kernels as well ? Eg, DEF1 , DEF2, and so forth....
