Windows 10: performance on generating a wim file

I have a WinPE bootable USB drive. After booting from the usb, I use
dism /capture-image /imagefile:E:\install.wim /capturedir*Biggrin:\ /ScratchDir:E:\Scratch /name:"AnyName" /compress:maximum /checkintegrity /verify /bootable
to generate a wim file. I got an wim file that is 6.5 Gbytes.
If E is a partition on a SSD hard drive, then it takes about 9 minutes to get the wim file; if E is a USB 3 flash drive, then it takes about 15 minutes to get the wim file.
Is it normal, and is there a faster way to get wim file? Thanks in advance.

Compacting a wim file?

Sorry, no idea where to put this. I just recently learned how to use dism. I use it to slipstream all hotfixes and ie10 ect into an AIO install disc. The problem is, it creates a huge install.wim after 8 index mounts and slipstreams. Considering all 8 images use the same darn wim and files, don't know why it has to increase the wim size by 1gig. Either I need to figure out how to use the same wim.install file for all indexes, or I need to compact the wim file which is now 4gbs with ie10 and all updates to April. Any way to do either?

 

Compacting a wim file?

Actually it turns out the answer is the dism that comes with Win8. Using the new Export-Image command, and a simple batch file, was able to compress my AIO wim by several hundred mbs.
