Device Info site freeze

i have problem with refreshing root of device. It looks like the tree is too big or something and site freeze i can’t click anything and only what i can do is close tab in browser. Before that i have problems with faults too many commit iterations and too many rpc request. I added to config:
cwmp.connectionRequestTimeout 512
cwmp.deviceOnlineThreshold 32768
cwmp.downloadTimeout 32768
cwmp.maxCommitIterations 256
it helps with faults but now everything freeze. Is this problem with performance? Can i tweak it?
