[PATCH v2 repost 4/7] virtio-balloon: speed up inflate/deflate process
...----------------------------------------------------------------------------------------------------
About the size of page bitmap, I have test the performance of filling the balloon to 15GB with a
16GB RAM VM.
===============================
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 performa...
