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. A revised compression stream format 2. Changed the xc_remus_* interface to a generic xc_compression_* format 3. Fixed issues like unaligned access, missing bounds check, etc 4. General code cleanups. Shriram
