Does wim compression define deployment speed?

Recommended Posts

I was wondering if the compression setting inside imagex (/compress none|fast|maximum) have anything to do with the speed of applying a wim file. Will setting compression to none make the apply operation faster or just the same?

 

Thank you.

I have never tried max compress, but I cannot tell the difference between none vs fast. From the Win7 WAIK:

While the compression type that you choose affects the capture time, it only slightly affects the apply time.

XPRESS (fast) decompression is measurable faster than LZX (max) compression

 

LZMS (recovery) decompression is much slower than all others.

What is this recovery? Is it the none parameter?

No, none really means no compression.

 

But you can use DISM and export a wim file to an esd file, than compression is called recovery.
