usage of APT_TSORT_STRESS_BLOCKSIZE environment variable

[hsahay]

Hi,

We would like to use APT_TSORT_STRESS_BLOCKSIZE to increase the memory usage and hence performance.

Can any one please tell us what is the default value,minimum and maximum values that we can assign for APT_TSORT_STRESS_BLOCKSIZE variable? i assume that the maximum value depends on the memory available with us. is my assumption correct? We could not find the details about this variable in product manual

Thanks for the help in advance
