Option -C <clients> 
You can use this function to set the maximum number of clients. The default setting is 800, the maximum value is 2039.
Note
Note that two clients correspond to one connection; that is max 400 connections are preset and max. 1019 connections are possible.
Note
If you want to run 1000 connections with your SAProuter, start SAProuter as follows:
UNIX/Windows: saprouter -r -C 2000
IBM i saprouter '-r -C 2000'
If you would like to have more connections than the maximum (1019), you can "move" SAProuter to another port with option -p and start a new SAProuter on this port.
Caution
These limitations are obviously only valid if smaller values for the number of connections have not been set in the operating system. Therefore you must take the operating system parameters into consideration.
Note
As of SAProuter version 37 significant higher values are possible, up to 16000 (with the exception of IBM i). But make sure that only one thread process is involved. For this reason having more than about 1000/1500 clients is not at all practical. With many connections you can work better with Option -Y <n>, which distributes the connections across several processes.
