Yandex hardware RND guys gave me ARM server and Power9 server. They are looking
for AMD and some new Intel boxes.
Meanwhile I made some enhancements to test suit:
1. I've added Shakespeare payload: concatenation of works of this prominent
poet.
2. For each payload compute "sliced time" - time to decompress payload if it
was sliced by 2Kb pieces or 8Kb pieces.
3. For each decompressor we compute "score": (sum of time to decompress each
payload, each payload sliced by 2Kb and 8Kb) * 5 times
I've attached full test logs, meanwhile here's results for different platforms.
Intel Server

From these results pglz_decompress_hacked looks best.
Best regards, Andrey Borodin.
