Slow connection issues and unstable latency or request timeout.

We have install 8 AP per floor and this building is a 4 stories building.
We have face slow connection issues and unstable latency issues or event request timeout.
Each AP is going to serve about less than 15 clients with uncontrolled traffic, mean they can do what they want including downloading p2p or torrent. But each clients is limited to 0.8Mbps download and upload speed.
Sometimes the clients can get about 0.7++Mbp but sometimes less than 0.1Mbps speed.
May i know what is the problem?
Here is the channel graph that i scan using mobile phone.
Is it AP place too closed and adjust too much power causing self interference?
Based on this graph, it is i am having self interference?

Co-channel seperation should be idially 20dB seperation between access points on the same channel at the edge of the cell. ex. AP01: -65dBm at edge of the cell & AP02 -85dBm at that same location.
