Calculating the I/O Response Times
The I/O response times are as follows based on the calculation results for the elements.
Formula:
Maximum I/O response time = Tcycle
×
2 + Extj + T#1-Free_I/OCycle
×
2
+ T#1-I T#1-Ou Tnx-InProc

+ Tnx-OutProc
×
2 + Tnx-I Tnx-Outdelay
= 500

2 + 7 + 100 + 379.64

2 + 0.10 + 0.30
= 2070.18

Formula:
Minimum I/O response time = Extj + T#1-I T#1-OutTrans
+ Tnx- Tnx-O Tnx-Indelay
+ Tnx-Outdelay
= 500 + 7 + 100 + 156.12 + 47.38 + 0.00 + 0.00 + 0.10 + 0.30
= 810.9
