[R] RMySQL: Slower parsing over time with htmlTreeParse()
Dear List, has anyone of you experienced a significant increase in the time it takes to parse an URL via "htmlTreeParse()" when this function is called repeatedly every minute over a couple of hours? Initially, a single parse takes about 0.5 seconds on my machine (Quad Core, 2.67 GHz, 8 MB RAM, Windows 7 64 Bit), . After some time, this can go up to 15 seconds or more. I''ve tried garbage collect, "catalogClearTable()" (though I don''t think that has anything to do with the issue) and lately wondered if it maybe had to do with the accumulation of errors over time ("xmlErrorCumulator()"). Are parsing errors cumulated globally in the workspace over distinct calls to this function? If so, is there a way to "clean the buffer"? I would greatly appreciate if anyone had an idea about how to keep request/parsing time fairly constant at the initial low level of 0.5 seconds. Thanks a lot, Janko [[alternative HTML version deleted]]
