7-zip supports several (seven according to its name) compression algorithms. So what are you talking about exactly?
E.g. the LZMA algorithm is high resource consuming one, specially with high compression level parameters (e.g. PPMd is much faster) - see the fabulous 7-zip manual for details.[/face]

Memo to Boss : No TC, No Work
This is what I get for not RTFM and just playing around with it on my own. I think, in your Multiarc setting, you have it defaulting to LZMA at Maximum (or possibly Ultra?) compression so it takes up 300 megs of memory to compress and I was, for reasons I can't even begin to understand now, testing on a directory containing 15 or so MP3s. This morning I compressed a few web directories which contained a mixture of text files (html, css, and xml) and graphics (jpg and gif) and I was quite pleased with the results against Zip.Black Dog wrote:[face=courier]7-zip supports several (seven according to its name) compression algorithms.

I noticed that whether I was using LZMA or PPMd, the speed seemed the same and the compression sizes were very close. However, I noticed that using LZMA, 7-Zip claims it requires less memory to decompress. I compressed an 8 meg directory down to 3.1 with LZMA @ Maximum vs. 4.5 with Info-Zip @ Maximum.
Good stuff.

Well, actually it looks like "-mx" stands for "Ultra" - it uses BT4b Match finder with 32 MB dictionary size so the memory used is 32*9.5+34 = approximately 338MB %).

LOL

It depends on compression parameters and data compressed. PPMd provides very good compression ratio for plain text files and LZMA is general compression method, so I guess this is not a good idea to compress e.g. executables with PPMd.
Memory used by PPMd set by "mem" parameter so you can compare it with memory used by LZMA. In most cases "mem156m" is enough.

___________transmission_from_7-zip.chm_____________
LZMA is an algorithm based on Lempel-Ziv algorithm. It provides very fast decompressing (about 10-20 times faster than compressing). Memory requirements for compressing and decompressing also are different (see d={Size}[b|k|m] switch for details).
[^Y]
PPMd is a PPM-based algorithm. [...] There is no difference between compressing speed and decompressing speed. Memory requirements for compressing and decompressing also are the same.

BTW, if you have P4 with HT you can add "mt=on" to increase LZMA compressing speed.[/face]

Hi !
* You can't pack files as *.CAB under Win 9x.
* M$ forced to change the name, they'ld give a CAB-licence to Ch. Ghisler to compensate this loss.
* So, I ought to use another program.

That's why I mentioned http://www.maximumcompression.com/
I have been trying to find something more serious that uses some of the compression standards like the Calgary Corpus, and of course, the latest versions of all compressors. But to no avail, nevertheles, this site has links to some experimental compressors that when they work, they put in shame everybody ie. Durilca. But, like I said... when they work. Please do not use them in something serious.
On the other hand, there is a new arrival that could challenge in the future all the other formats, it is "WinRK" ( http://www.msoftware.co.nz/ ). At this moment it is still "young" and needs a lot of work, but it is showing promises.

Hi !
• Certainly, thanks for the info, but isnt' very cheap, with regard to its "youth" : ~ 23 € / 27.5 US$ for one licence, that is almost the price of TC !
* Hoping it'ld get cheaper when more known and spread…

It's not such a newcomer. RK 1.04 alpha 1 was released in the late year 2000 and even before there's been RKIVE.there is a new arrival that could challenge in the future all the other formats, it is "WinRK"
