Could someone help optimize this for Mathematica 9?

We have a strong need to view large numbers of data points. Mathematica 8 was excellent at this. The following code executed under both 8 and 9 (Windows):
Mathematica 8: Less than 0.5 seconds
Mathematica 9: Greater than 4 seconds
mNumberSamples=100000;
mFrequency=10;
m=Table[{t/mNumberSamples ,Sin[t/mNumberSamples mFrequency*2 \[Pi]]}*1.0,{t,1,mNumberSamples}];mStartTime=SessionTime[];
ListLinePlot[m]
mStopTime=SessionTime[];
StringForm["Elapsed time = ``", N[mStopTime-mStartTime]]
I have tried the code on a slower mac laptop (version 9 only) and had the same slower results. Any input welcome as this functionality is extremely important to us.
