I am a heavy user of Boom 2 for Mac, which is an awesome virtual amplifier and equalizer for OS X. With version 1.2, a new feature called Boom Remote lets you control Boom from an iOS device. I am not using this feature, but I guess that it is very welcomed by iOS users.
Unfortunately, at least in my case (2015 Macbook Pro 13″, OS X 10.10.3) Boom Remote halves my Internet connection speed. It took me quite some time to understand what was causing this issue, as all my other devices were working well and you would not really look at a sound app for connection issues. The only way to fix this for me was to disable Boom Remote completely.
The video demonstates the issue and the fix.
First, you will see a speedtest with Boom Remote turned off. The download speed at this point is 13.59 Mbps. However, when repeating the speedtest with an activated Boom Remote, the download speed goes down to 6.92 Mbps! To further show the issue, a third speedtest is run with Boom Remote turned on, then suddenly off. The connection speed increases rapidly right after the feature is turned off.
I let Globaldelight know about the issue. In my case, I can live without Boom Remote. Hopefully, they will fix it soon for other users.
