v.status v.status reports the current processor requirements of various parts of the softVNS system and allows performance tuning. v.status reports the current processor requirements of various parts of the softVNS system and allows performance tuning. softVNS 2.1 calculates the total processing power required to process all streams at the currently set frame rate. If this amount is larger than the max_percent value, then softVNS ignores a certain number of frames per processed frame so that the actual processing percentage is less than max_percent. This effectively reduces the frame rate of the system. Note that if you are running a very complex MSP patch along with softVNS, and your softVNS streams are not running in overdrive or on quicktime interrupts (i.e. if you are using the v.movie object or v.dig in seq_grabber mode) the processing time reported may be more than it actually is, since other processes using interrupts will add their processing time to softVNS's.
