Thumbnail Generation Only Uses 1 Core

[shedletsky]

I have 44GB of iphone photos in a folder.

It would seem that XnView MP only uses 1 core for thumbnail generation. I have 16 cores and two SSDs in RAID 0. I'm getting thumbnail throughput of 2 MB/s. It makes me sad.

Is there a secret setting somewhere to increase parallelism of thumbnail generation?

yes, currently only 1 core is used
