Install Speed Inno Vs. InstallAware 18

[mikKummerfeld]

Hey Guys,

i have completed the migration from inno setup to IA and it works perfectly now.
I didnt used the converter, I rebuild the project.

Now my customer is really angry because the install speed is very bad:

1. Loading process until first welcome dialog:
Inno: 6 seconds
IA: 31 seconds!

2. Install progress:
Inno: 15 seconds
IA: 48 seconds

How can we improve the speed? I tried all compression levels, but it is very slow.
LOADCACHE is also TRUE.

Do you have any idea? Would be nice

Dear Heiko,

as first, it's quite impossible to compare the two "different" engines in pure terms of "speed" performance.

The time required by the initialization process mostly depends on the compression level used. Greater is the compression level than more it will be the time required to decompress the setup files.

For what concerns the rest and without knowing what your setup "exactly" does at install runtime, it is really difficult to say if your speed performance can be improved.

Regards.

The written times are with compression Level 0 (No compression).
The Setup is very simple and from a template.

What can I also do to improve the process in Speed?

I can give you the Code maybe you see something?

Dear Heiko,

as I said previously, it's quite impossible to compare the two "different" engines in pure terms of "speed" performance and of course, you cannot reproduce the same performances.

If you are just installing some files, I don't believe that there is anything that you can do.

Regards
