Origin 9.1 SR0

...

• ORG-10120 Graph rending slower than 9.0 or 8.6. – fixed in 9.1 Sr1
  In 9.1, if the project contains curve with large width and large amount of data points (>2000), Origin would run much slower. It doesn't happen for 8.6 or 9.0.
  Work around: set system variable @LP=700 by choosing Tools: System Variables menu.
