Tested under xen-4.2-unstable. A simple benchmark: SpecJBB (Java Benchmark) - 4 minute Remus run, with PV domU (2.6.32 xenolinux kernel), 1G memory and 2 VCPUs - Data sent without compression: ~70GB. - Data sent with compression: ~8GB. Changes since last version: 1. Added some more sanity checks and bounds check to the decompression code. 2. Bit of code cleanup. 3. Merged the wire protocol documentation and the libxc compression patch 4. Added comments to xc_domain_save.c, explaining the use of two outbufs. Shriram
