4k HEVC encoding always will take quite some time with that CPU.
Since you are using lossless encoding picture quality will always be as high as it gets, but file size will be huge.
Using slower settings for motion search etc. will decrease the file size but slow down the encoding.
Using faster settings for motion search etc. will speedup the encoding but increase the file size.
-> Choose your poison.

Ps.: Personally I wouldn't use lossless encoding and probably go with a crf of 16 or lower, but that depends on what you want to use that encoding for. As intermediate lossless should be fine, but be aware that no hardware decoder I know of currently can decode lossless HEVC. So playback will be cpu intensive.
PPs.: depending on the content you can try different resizes and see there differences (which should be minimal for most)
