When I run Android SDK manager to download SDK platform, the download speed is 8 KiB/s. It would take more than 2 hours to download one platform like Android 2.2, API 8. There is no problem with download stuff through browser. Does anyone know how to fix this problem?
I have not experienced this issue. Force or unforce HTTPS (there is an option for this under Settings), and see if this improves the quality of your connection.
