Why is dolphin so slow at extracting an iso?

[Melvin8D]

I was extracting an Iso for modding, but when I see the time left, its 30 minutes to 3 hours??? And when I go to task manager and look at dolhpin, I see it only has a transfer rate of 1mb\s to 0.1mb\s. My hard drive can easily handle a 20mb\s transfer rate. It has even gone up to 90mb\s write speed with 7zip, even tohough my hdd is very old. Why is it so slow?

Idk , I just extracted The Last Story (5GB) , it took only 2-3 mins to do so .
I store game on USB 3.0 HDD and extract game on the same drive . On SSD , it's even faster , less than 1 min or so

I have the same experience as admin89, I've never had the ISO extraction take a very long time. I'd say either your hard drive is really bad or you have some other process eating at your disk I/O.

What's the model of your HDD if you don't mind my asking? Perhaps we could better assist you if we knew what we're working with.
