Does Local Mining interfere with Cloud Mining Hash Speed?

[JohnnyPierce]

What the title says, I have found that when all my droplets are running via Putty SSH (approximately 25 Droplets) my hashing speed is about 350 Kh/s, but when I turn on my GPU mining, the hashing speed on the pool keeps the same average speed, if I check the workers indepedently, I find that when I turn my GPU on, the cumulative speed of the cloud drops to about 50%.

And vice versa, when I have my GPU mining along with my cloud droplets, my GPU speed is about 200 Kh/s, but when I close all my droplets, my GPU speed rises to about 350 - 400 Kh/s

Is this normal, why is this happening?

Does anyone have any idea why this is happening, supposedly cloud mining shouldn't take any resources away from the computer, so why is my hashrate being crippled when I turn my GPU in association with the SSH droplets?

Also, I have tried running cgminer in this computer and the SSH droplets in another computer, and I managed to achieve nearly 700 Kh/s in the mining pool stats.

This problem only happens if I use both options in the same computer, but I'd like to know why is this the case? Why this interference considering that cloud mining is being done remotely?
