How to estimate the buffering time from the buffering capacity is shown below.
Buffering time = (Allowable No. of bufferings)
Allowable No. of bufferings = (Capacity to be used)
SQL text length = Total field character length + 6
[Calculation Example]
In the case of the capacity of 64 Mbytes, the field name of 16 characters, the data length of 32 characters, access to 256 fields by
one action per job, and executing once per 30 seconds
SQL text length = (16
Allowable No. of bufferings = (64
Buffering time = 4846
