Title: Compressed DLLs
Post by: kryton9 on August 11, 2012, 10:45:27 PM

I tried upx on oxygen.dll and freeglut.dll and reduced their size by a good bit. Here is a test of them.
oxygen.dll 416kb down to 135 kb
freeglut.dll 210kb down to 66kb

I put upx in the zip file too.

Open a command prompt type:
upx -9 dllNameOrExeNameWithExtention

Thanks Kent. Interesting!

standard zip compression takes Oxygen.dll down to about 180k, so it offers around 20% further compression, even with the loader overhead.

One format missing on their list though: win64.

Nowadays we have more than 1 Terra Byte Harddrives.
And Kent is packing 138.0 KB with UPX !

Is your Hd only 1 MB ?
Upx isn't  interesting. Maybe, some years ago. (1805-1939)   :D

Peter,
 It is not about local storage but about deployment.
I find upx very useful with statically linked wxWidget apps.

This simple ubx example comes in at 2,358,784 bytes.
after ubx -> 702,464

Hi James,

2,358,784 bytes isn't that much.
It's only a pack rate of 3,35%  !

I have used UPX in the past very often.
I didn't say is bad, only unnecessary.

I just found it interesting it worked on DLL's also and did quite a nice job.

I don't prefer compressed stuff because in the past i have some
nasty security problems ...in first place with UPX... >:(
