I think what i did is the same with you except i use make rather than make -sj8, and I did as root. And I do as you wrote again: root at hurricanetong-VirtualBox:/home/hurricanetong/xapian-1.2.17/xapian-core-1.2.17# ./configure [...] root at hurricanetong-VirtualBox:/home/hurricanetong/xapian-1.2.17/xapian-core-1.2.17# make -sj8 Making all in .

I've just built trunk (on Mac OS, admittedly), and your code comp...

...er is 12592387, while that by InterpolativeEncoder is 8554817. When only encoding the first 1000lines, both cost 0ms to decode and VS cost 1ms to encode while Interpolative cost 0ms, 1000lines is just too little to catch the difference in my test. I upload the source code to https://github.com/HurricaneTong/Xapian/tree/master/VSEncoder The bitstream.cpp and bitstream.h is about VSEncoder. The Interpolative.cpp and Interpolative is about InterpolativeEncoder from the Xapian's code. I haven't write comment on the code, but in main.cpp, double CalTimeVS( const vector<unsigned int>& src...
