I can tie up my familiar patterns I use fairly quickly but I'm not doing them quickly these days . I have no reason to rush, I might walk away from the vise and put on a pot of coffee, then come back etc... Even go cut the grass with the bobbin hanging off the half finished fly lol ! In Maine with the river waiting and two boys out of caddis flies I whipped up half a dozen Elk Hair Caddis in 30min while one son cooked breakfast and the other tied BWO. But EHC are pretty easy to tie and we had tied dozens of them over the years, knew the pattern well , the materials were on hand because I had just tied some earlier in the week etc.
I'm retired now,I don't feel the urgency.
