Stuttering in game modes after update

After your latest update all fleet-arena fights are stuttering like crazy. Every attack/debuff applied freezes the screen for a moment.
Did you perhaps add some stupid logging functions that destroy the experience, or maybe forget to turn them off?

Also your 5 second auto-update on certain screens is still there. I bet that's why the shops were lagging. Are you deliberately trying to DDoS your own servers? Do you like paying the extra money for data transfer/CPU?
