Thanks for providing an in-depth, data driven analysis. It is surprising that zlib provides better compression at the high end. I wonder if that is due to our specific data patterns - many zeroes - which probably puts us into the zlib dictionary fast path. On Sat, Nov 28, 2015 at 4:41 PM,

[bitcoin-dev] Test Results for : Datasstream Compression of Blocks and Tx's

2015-11-28 Thread Peter Tschipper via bitcoin-dev
Hi All, Here are some final results of testing with the reference implementation for compressing blocks and transactions. This implementation also concatenates blocks and transactions when possible so you'll see data sizes in the 1-2MB ranges. Results below show the time it takes to sync the
