    if you find lots of such lines, or even worse, if they appear systematically, then chances are that you're using a plugin which does systematic updates to the configuration file ([TracIni trac.ini]), and this will in turn trigger a full environment reload at the next request. That can slow down the performance a lot, to the level of TracCgi. See ticket:7490#comment:102 and follow-up.

    if you find such lines ''and the `cached rev` value doesn't change'', this corresponds to a repository resync failure which results in a resync attempt for every request (see ticket:7490#comment:36); often due to the "prohibited" MySQL/MyISAM combination (#8067)
