Instruction cache and QSPI XIP performance

I am exploring the QSPI XIP performance for an MQX application running on a TWR-VF65GS10 processor board. I added the capability to enable and disable the instruction cache.


if ( value )





The execution performance is the same for either setting. What would account for this behavior? Does the instruction cache help QSPI XIP performance?
