Почему система становится отстающей при соединении с Интернетом?

То, почему, когда я соединяюсь, мой нетбук к Интернету через LAN или Wi-Fi делает целую систему, становится отстающим? Даже когда в неактивном, монитор ЦП показывает 100%-е использование при подключении. У меня была эта проблема о половине года теперь, так как я установил Ubuntu 11.10.

Я в настоящее время использую Ubuntu 12.04 LTS на нетбуке Спутника Toshiba NB-105 с 1 ГБ RAM и 1 процессора GHz Intel Atom.

Вот мой syslog:

Предложение следующего agc93 для проверки, какие рабочие процессы являются самыми интенсивными ЦП похоже, что это - gwibber.service, сопровождаемый Google Chrome и Ubuntu Один. Что я должен сделать об этом?
