perma-link to the smallest file on my server:
http://minime.stephan-brumme.com/files/vue/vue-2.0.6.min.js

You will automatically get the smallest Vue 2.0.6 file, ETag caching is available and
if your browser doesn't support GZIP decompression then the uncompressed version will be sent.

Currently best Zopfli settings

Save 860 bytes by using my Vue 2.0.6 Zopfli version instead of the best available CDN (3.63% smaller than jsdelivr, 23674 vs. 24534 bytes):
You can use my super-compressed files for whatever purpose you like as long as you respect the library's original license agreement.
There are no restrictions from my side - but please avoid hot-linking if you run a high-traffic website.

These command-line settings yielded the best compression ratio so far (Linux version of zopfli-krzymod):
zopfli --i100000 --mb8 --mls4096 --bsr16 --lazy --ohh

Heatmaps

This Zopfli heatmap visualizes how compression changes when modifying the --bsr and --mls parameter.
Cell's contents is the best filesize achieved (in bytes, hover with mouse over cells to see number of iterations).

Good parameters are green, bad are red. The best and worst are bold as well.
The brightness of the blue background color indicates how many iterations were processed:
10,000 or 100,000.

Due to the Monte Carlo design of my search algorithm, not all parameters have reached the same number of iterations yet:
Iterations Min. Bytes Reduction Coverage
100 23686 bytes 100%
1,000 23683 bytes -3 bytes 100%
10,000 23677 bytes -6 bytes 100%
100,000 23674 bytes -3 bytes 1.74%
1,000,000
10,000,000

KZIP has far less options available for tuning/optimization. I only played around with the number of blocks (parameter -n):
Blocks Min. Bytes Compared To Best Zopfli Compared To Best KZIP
23775 bytes +101 bytes (+0.43%) +6 bytes
23777 bytes +103 bytes (+0.44%) +8 bytes

23769 bytes +95 bytes (+0.40%)
23777 bytes +103 bytes (+0.44%) +8 bytes
23808 bytes +134 bytes (+0.57%) +39 bytes

23850 bytes +176 bytes (+0.74%) +81 bytes
23882 bytes +208 bytes (+0.88%) +113 bytes

Non-DEFLATE Algorithms

Archivers based on completely different compression algorithms often produce superior results.
Unfortunately, browsers only support gzip compression at the moment.

Detailled Analysis

I wrote a DEFLATE decoder in Javascript. Click the button below to start a client-side analysis of the smallest gzipped files (may take a second):


Notes: pigz is a fast open source multi-threaded implementation of gzip written by one of the original authors of gzip.
However, when using compression level 11, pigz actually switches to the slower Zopfli algorithm and isn't multi-threaded anymore.
KrzyMOD's extensions to Zopfli offer the highest level of configuration and is therefore used for my brute-force search.
Ken Silverman wrote the closed-source KZIP compression program and Jonathon Fowler ported it to Linux.
Defluff was created by Joachim Henke; DeflOpt is a tool by Ben Jos Walbeehm.
