Compression

[NewsArchive]

Friedrich,
At some point when you get bored... <G>

I usually make installers with compression set to maximum.

But when an installer contains a large .CHM or .PDF file, that can be a
waste of a lot of processor cycles.

Would it be possible to add a "don't compress this file" check box in the
files attributes section?

Jane,

I've not played with that (yet). What is the difference in time?

Jane,

Unfortunately, this is not possible (at the moment). The "compression"
feature does not only compress the file, it also encrypts the data and
brings it into a specific binary format (to support disk-spanning,
file-skipping, etc.). The compressed/encrypted data stream is vital for
file handling process. An uncompressed data stream (e.g. an ASCII text
file) would break the whole system.

Nothing empirical, Russ. And I think likely what I'm seeing is differences
in time to timestamp the code-signing (commodo's timestamp server sometimes
takes longer than verisign's, it seems).

I turned off code-signing and tried making an installer that includes a 17MB
CHM file.

Total data size was 43.14 MB

(without code-signing):
Fast compression: 8.67 secs. installer 31.00MB
Standard: 10.03 secs. 30.45 MB
Maximum: 17.02 secs 30.35 MB

Then I made a installer that ONLY has the 17 MB CHM file:
total data size: 16.94 MB
Fast compress 27.77 secs 17.05 MB
Standard 26.01 sec 17.05 MB
Maximum: 24.4 sec 17.05 MB

Now I'm more confused, and am just going to pretend I never posed this
question <G>
