Do you cap your upload/download? Why or why not?

I want to turn off my PC but I'm the only seed for an unpopular linux distro. The downloader obviously has it capped at 1MB/s so it's crawling slowly... just a couple minutes now...

I have my download at 10MB and upload at 5MB. I don't want to hog all the bandwidth from my family and I don't need it any faster anyway. I never see the upload reach the cap.
