Dependence of PclZip

[wapmorgan]

Hello. I see all your projects dependence on this package and this package use pclzip. I think pclzip is very slow solution in case of managing zip-archives. As alternative for this I can support using my package (https://github.com/wapmorgan/UnifiedArchive). It provides all needed functions to work with zip archives with very big speed gain (comparing to PclZip). Also, you don't need to change all things that work with archives, only initiation part. Let me show.
It provides PclZip-like interface for ZIP archives, so all you need is to change PclZip initiation

$archive = new PclZip("archive.zip");

to UA initiation and receiving PclZip-interface

$archive = UnifiedArchive::open('ziparchive.zip')->pclzipInteface();

That's all! After that speed of all archive operations will increase.

Take your time to think that and I can help you test your products and replace old requirements with modern ones.

To approve my words about PclZip oldness there's results of some benchmark. I took few popular projects on Github as zip-archives and few my archives and tested full extraction with UnifiedArchive and PclZip.
To avoid storage latency impact on test I used in-memory disk (imDisk) for Windows and created a 3Gb virtual hard drive, copied all archives to it and start testing (avg write/read speed is 3Gb/sec).

My results are:
1st run

Filename	UA (time)	% of PZ	PZ (time)	UA (mem)	% of PZ	PZ (mem)
googletools.zip	0.047	86%	0.054	1.18m	99%	1.18m
PHPWord-develop.zip	1.030	43%	2.344	1.3m	109%	1.19m
turbosale_1.0.0.zip	0.545	66%	0.817	1.23m	103%	1.19m
meteor-devel.zip	11.237	86%	12.968	1.76m	148%	1.19m
subrion-develop.zip	19.045	92%	20.684	2.03m	171%	1.19m
OptiKey-master.zip	3.257	85%	3.807	1.34m	112%	1.19m

UA is 24% faster

2nd run

Filename	UA (time)	% of PZ	PZ (time)	UA (mem)	% of PZ	PZ (mem)
googletools.zip	0.042	83%	0.051	1.18m	99%	1.19m
PHPWord-develop.zip	0.876	43%	2.007	1.3m	109%	1.19m
turbosale_1.0.0.zip	0.537	75%	0.714	1.23m	103%	1.19m
meteor-devel.zip	10.032	83%	11.964	1.76m	148%	1.19m
subrion-develop.zip	15.329	86%	17.772	2.03m	171%	1.19m
OptiKey-master.zip	3.023	79%	3.791	1.34m	112%	1.19m

UA is 26% faster

and 3rd run

Filename	UA (time)	% of PZ	PZ (time)	UA (mem)	% of PZ	PZ (mem)
googletools.zip	0.037	77%	0.048	1.18m	99%	1.19m
PHPWord-develop.zip	0.897	43%	2.065	1.3m	109%	1.19m
turbosale_1.0.0.zip	0.530	73%	0.726	1.23m	103%	1.19m
meteor-devel.zip	10.424	85%	12.230	1.76m	148%	1.19m
subrion-develop.zip	15.425	83%	18.406	2.03m	171%	1.19m
OptiKey-master.zip	3.102	83%	3.716	1.34m	112%	1.19m

UA is 26% faster

Average growth is 26% when storage latency is very low!

If test the same archives on usual HDD (avg read speed is 120mb/sec), I get that result:

Filename	UA (time)	% of PZ	PZ (time)	UA (mem)	% of PZ	PZ (mem)
googletools.zip	0.014	67%	0.020	1.18m	99%	1.19m
PHPWord-develop.zip	0.573	63%	0.907	1.3m	109%	1.19m
turbosale_1.0.0.zip	0.250	80%	0.309	1.23m	103%	1.19m
meteor-devel.zip	6.553	62%	10.429	1.76m	148%	1.19m
subrion-develop.zip	10.682	82%	12.996	2.03m	171%	1.19m
OptiKey-master.zip	3.445	82%	4.180	1.34m	112%	1.19m

UA is 28% faster

@wapmorgan Don't hesitate to create a PR for adding an adapter for UnifiedArchive : https://github.com/PHPOffice/Common/tree/develop/src/Common/Adapter/Zip :)

Ok, then this issue can be closed.
