This is with the same filters set for both uBlock and uBlock Origin.  It seems something specific to uBlock Origin that is taking a very long time to load that does not exist in uBlock.  \r\n\r\nDuring the 35 - 45 seconds of waiting with uBlock Origin, Firefox is using ~15% processing power consistently.  This is on a Windows 8.1 machine with Firefox 38.0.5 (latest).

The bug report is mainly that uBlock Origin is taking 35-45 seconds (much longer than no plugins, and much longer than uBlock -- both about 10-15 seconds).  \r\n\r\nMy ublock0.sqlite and ublock.sqlite files are both about 9MB in size.  \r\n\r\nFor h/w specs: \r\nIntel QuadCore 2.7 GHz, 16 GB RAM, Seagate Momentus Hybrid @ 7200 RPM "}}
