Quote from Bernard111:
Should I force the java applications to use the 6 with the checkbox within JNLP Runtime Settings under the column 'Enabled' (Java - Java Application Runtime Settings / View), so the 1.6.0-rc is the only Java Sun running (unchecking the other javas previously installed)?

Quote from JDO_Trader:
I didn't have to do that Bernard. In TWS, if you go to the "help" menu then choose "About Trader Workstation" at the bottom a screen comes up and says which version of Java is being used. Mine says: 1.6.0-rc

Thanks for the heads up. I will give the new java VM a try, but I have noticed that for my applications anyway, my CPUs rarely goes above 10% (on a Quad Opteron machine) when running TWS.
That may be because all I am doing is the standard TWS grid and API, and no charts and fancy analytics running...
