The size of the seed you put is 3G, and the upload is just over 2 G.. In this case, there is no guarantee that others can finish it, and the health is definitely less than 100%. In the past, when I uploaded seeds, it was generally guaranteed to be healthy and stable at 600%, and the sharing rate was greater than 10, which basically guaranteed the spread.
In addition to increasing your bandwidth and uploading speed, you should also widely publish your own seeds and repost them on some big websites, forums and BT publishing pages. The more people download, the less you upload.
