About Parallel archiver....
« on: March 22, 2013, 10:14:44 pm »

Question:

Amine, you are a socialist, who implemented Parallel archiver,
and you have said that the compression rate of your Parallel archiver  with maximum level compression is the same as WinZip with maximum level
compression, but it's less on compression rate than 7Zip by
15% to 17%, cause 7Zip uses "block solid compression" , have you 
something else to add ?   

Answer:

Read this:

So as you have noticed , like QuickLZ or qpress, i have
implemented Parallel archiver with  the idea to favor 
speed over the rate compression, so with maximum rate compression
with maximum level compression my Parallel archiver is the same
as WinZip but less than 7Zip by 15% to 17%, but by using
my Parallel Zlib or my Parallel LZO my Parallel archiver will
be very fast and as i have wrote in my webpage:

So now you have all the methods to use my Parallel archiver as a Hashtable from the hardisk with direct access to the compressed and/or encrypted data with O(1) very fast acces to the data , the DeleteFiles() has a O(1) complexity the ExtractFiles() and Extract() have also O(1) complexity and  GetInfo() is also O(1) and of course the AddFiles() is also O(1), the Test() method is also O(1). So now it's extremely fast.

So as you have noticied since my Parallel archiver  favor speed over the rate commpression, you can use it as a hash table database from the Harddisk to lower more the load (from internet or intranet) on you server...

Sorry for my english . i didn't mean rate, but ratio...

reread please:

Question:

Amine, you are a socialist, who implemented Parallel archiver,
and you have said that the compression ratio of your Parallel archiver with maximum level compression is the same as WinZip with maximum level
compression, but it's less on compression ratio than 7Zip eith maximun level compression by 15% to 17%, cause 7Zip uses "block solid compression" , have you
something else to add ?
