14.04 bluetooth lag (latency, delay) and skipping

i came across:

2. Pulseaudio not detecting bluetooth headset automatically
3. How to get a consistent bluetooth audio playback? (didn't help me)

i can direct audio to my bluetooth device, though i experience lots of skips.

$ tail -n 100 /var/log/syslog | grep -i bluetooth Aug 2 22:29:56 orion pulseaudio[3227]: [bluetooth] module-bluetooth-device.c: Skipping 209917 us (= 37028 bytes) in audio stream Aug 2 22:30:01 orion pulseaudio[3227]: [bluetooth] module-bluetooth-device.c: Skipping 293454 us (= 51764 bytes) in audio stream Aug 2 22:30:08 orion pulseaudio[3227]: [bluetooth] module-bluetooth-device.c: Skipping 80787 us (= 14248 bytes) in audio stream Aug 2 22:30:17 orion pulseaudio[3227]: [bluetooth] module-bluetooth-device.c: Skipping 258969 us (= 45680 bytes) in audio stream Aug 2 22:30:17 orion pulseaudio[3227]: [bluetooth] module-bluetooth-device.c: Skipping 181144 us (= 31952 bytes) in audio stream Aug 2 22:30:37 orion pulseaudio[3227]: [bluetooth] module-bluetooth-device.c: Skipping 46465 us (= 8196 bytes) in audio stream 

here is more information about my system:

does anyone know how to resolve this issue?

UPDATE:

when i turn on the wifi i experience these errors, whereas with wifi off, no such skipping occur.
