qcow2 support compress option to compress image file. I try to read both files through API by libguestfs(such as pread_device)
I'm confused with the performance during read or write I tried to compress A.qcow2 to A_compress.qcow2 and it changes from 16GB to 23MB I tried read on A_compress.qcow2, it seems faster than A.qcow2 maybe something wrong happened?
