1 Use multiple thread (de)compression in live migration
21 be decompressed. Using compression in live migration can help
27 The process of compression will consume additional CPU cycles, and the
30 the total migration time. If the process of the compression is quick
32 thread compression can be used to accelerate the compression process.
35 compression, if the source and destination CPU have equal speed,
36 keeping the compression thread count 4 times the decompression
39 Compression level can be used to control the compression speed and the
40 compression ratio. High compression ratio will take more time, level 0
41 stands for no compression, level 1 stands for the best compression
42 speed, and level 9 stands for the best compression ratio. Users can
46 When to use the multiple thread compression in live migration
48 Compression of data will consume extra CPU cycles; so in a system with
51 multiple thread compression will be very helpful. If both the CPU and
52 the network bandwidth are adequate, use of multiple thread compression

112 to support the multiple thread compression migration:
116 2. Activate compression on the source:
119 3. Set the compression thread count on source:
122 4. Set the compression level on the source:
141 thread compression in migration. You can do more if the default
146 Some faster (de)compression method such as LZ4 and Quicklz can help
147 to reduce the CPU consumption when doing (de)compression. If using
148 these faster (de)compression method, less (de)compression threads
