Does Winrar support multiple cores?

When extracting files from archives I notice that CPU usage is really low, like 15-25%, does winrar not support multithreading for extraction?

The thing is it's not being hdd limited here, it's taking 6mins to extract 5.2GB of data.

The website just mentions compression, which is why I asked here.

On a HDD with an 80MB/s rate it should take less than half that time surely? Copy 4GB of data to ram ~ 50 secs, copy to hdd 50 secs, then copy 1.2gb to ram ~15 secs, then to hdd 15 secs, totalling 130 secs, as opposed to 360.

It doesn't copy it all to ram, it copies it to a temp folder iirc

Isn't that incredibly inefficient though? It means reading and writing at the same time which significantly reduces throughput.

and surely unless you have over 6 gb of free ram,then the swap file would be needed anyway for a 5.2gb archive....probably 12 gig thinking about it...

You could copy it in segments, say 100MB, 1s to copy to memory and then 1s to copy to hdd.
