Hi all, over the holidays, I played around with processing some gzipped json data. First version was implemented in ruby, but took too long, so I tried, dlang. This was already faster, but not really satisfactory fast. Then I wrote another version in java, which was much faster.
After this I analyzed the first step of the process (gunzipping the data from a file to memory), and found out, that dlangs UnCompress is much slower than java, and ruby and plain c. There was some discussion on the forum a while ago: http://forum.dlang.org/thread/pihxxhjgnveulcdta...@forum.dlang.org The code I used and the numbers I got are here: https://github.com/gizmomogwai/benchmarks/tree/master/gunzip I used an i7 macbook with os x 10.13.2, ruby 2.5.0 built via rvm, python3 installed by homebrew, builtin clang compiler, ldc-1.7.0-beta1, java 1.8.0_152. Is there anything I can do to speed up the dlang stuff? Thanks in advance, Christian
