Hello,
I would like to know the exact purpose of the variable MCR_CACHE_SIZE? My compiled app is around 40 Mb. I have read that the default MCR_CACHE_SIZE is 32 Mb. Does this mean that I need to set the MCR_CACHE_SIZE to a greater value to avoid issues during execution? If I need to increase the cache size, what is the syntax? set MCR_CACHE_SIZE="64Mb"?
Thx in advance,
Luc Masset

Hello Deepak,
Thank you for your answer. Eventually I set the variable MCR_CACHE_SIZE to 64 Mb in the command file used to launch the executable (set MCR_CACHE_SIZE=67108864). However I have also tested a value of 2 (2 bytes) and it does not seem to change anything.
Regards,
Luc

How are you measuring the execution time of your App? May be, your App size is small and hence you are not observing any noticeable change in the execution time.

You can set the size of MCR_CACHE_SIZE environment variable by editing the .max_size file which resides in the current cache directory (which can be found by executing the following command at the MATLAB command prompt)
>>mcrcachedir
As per my understanding, increasing the MCR_CACHE_SIZE might help to speed up the execution of your program.
Refer the below documentation link for more details :
