[PATCH v2 repost 4/7] virtio-balloon: speed up inflate/deflate process
...===========================
32K Byte (cover 1GB of RAM)
Time spends on inflating: 2031ms
---------------------------------------------
64K Byte (cover 2GB of RAM)
Time spends on inflating: 1507ms
--------------------------------------------
512K Byte (cover 16GB of RAM)
Time spends on inflating: 1237ms
================================
If possible, a big bitmap is better for performance.

Earlier you said:
a. allocating pages (6.5%)
b. sending PFNs to host (68.3%)
c. address translation (6.1%)
d. madvise (19%)
Here sending PFNs to host with 512K Byte map
should be...
