How long should my readers take?

I recently wrote a long short story, 11,000 words. I wanted to get a round of crits (and do more revisions if needed) before sending it out, but I am getting impatient!

I sent the story to three writers I know IRL, one of them from the distant past, the other two from writer's groups and workshops. I have a fourth reader who wants me to deliver a printout to him tomorrow. The others got the story about 10 days ago through the email. I know that everyone is busy, and that it's kind of a long piece, but I don't think it will take that long to read. I want answers already! I should add that two of these people are published authors, and one of those is someone I definitely look up to as a writer, though I also see her as being somewhat in my peer group.

How long should I be patient for before bugging them?

I did get my husband to read it last night, and he had a few thoughts about the plot (adding some scenes) so that's something. He also confirmed my feeling that despite the word count it doesn't take long to read.

I will ask the guy I give it to tomorrow to do it within a few days' time, maybe by Monday.

Georgiana: I talked to one of them about it months ago, early in the summer, and he offered to look at it then. The others I asked (2 via email, one in person). I only sent it to those who said they would read it.

I think I made it clear that I was looking mostly for general comments, not a line edit.

I will wait another week before asking them... and yes, I know that turn-around times on submissions to markets are slow, but at least there I can get a good idea of what to expect from Duotrope and the publications' own websites.

Update:

I got the hard-copy crit back on Saturday night/Sunday morning, and sent the others a nudging email yesterday morning. 2 of those have gotten back to me, one has promised it by tomorrow.

On to the final (?) rewrite!
