A very common issue among Google Drive users is that there is no way to limit upload speed of Google Drive syncing process. Problem typically manifests by rendering user’s Internet connection unusable, due to sync process taking 100% of the upload bandwidth. In such case you’ll observe that you cannot browse the Internet (or it’s extremely slow), even that your download bandwidth is fully available. Issue can be overlooked if you’re only uploading small amounts of data here and there, but if you’re uploading gigabytes of information, it can take days or weeks. Anyhow, there is a way to fix this problem and that is to limit the upload speed of Google Drive process.
This important feature has never been implemented by Google, so keep in mind that this is just a workaround.
