IB - TWS with latest Java

Quote from kiwi_trader:

1.6.0_10 is a major revision. Performance and reliability focus.

got a link for Java Version 1.6.0_10-rc2 download? thanks


edit: nm found it
 
Has IB Finally endorsed and suggested JVM version 6 ?
It's only been out now like 2 years.....and was too buggy for IB to recommend ?
 
never wait for recommandations... always be on latest versions....
for me that worked out for everything until now :-)))))
(if wont work, change back to older version.....)

Upgraded Wed. Works like a charm. Thanks for the heads up.

I've been running it for a week now. Very nice (I use it in Server VM mode with draw turned on).

Code:
Run ( 'C:\Program Files\Java\jre6\bin\javaw.exe -cp jts.jar;pluginsupport.jar;jcommon-1.0.12.jar;jfreechart-1.0.9.jar;jhall.jar;other.jar;riskfeed.jar;rss.jar -Dsun.java2d.noddraw=false -server -Xss128k -Xms256m -Xmx256m -XX:NewRatio=3 -XX:+ForceTimeHighResolution -XX:CompileThreshold=50 -XX:ThreadStackSize=192 -XX:+AggressiveOpts -XX:+UseFastAccessorMethods -XX:+RelaxAccessControlCheck -XX:MaxInlineSize=8192 -XX:-DontCompileHugeMethods -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:+ExplicitGCInvokesConcurrent -Xnoclassgc jclient/LoginFrame R:\JTS', 'R:\JTS' )

Kiwi, thanks for sharing your startup command for TWS startup. I think I will try to be a copy cat and see how it goes. Right now I am very curious about what all these "-XX:+......" swithes do, and how they impact the way TWS runs. Can you tell us a little more about why you included them in the startup command? Thanks again.
 
Someone else started a discussion thread about java/tws performance a year or so back. I started with what he suggested and then (by googling the commands) made some adaptions for faster real time performance at the expense of more memory use.

Is this code run from within tws or windows cmd?

I copied the server folder where you said to and ran the code from cmd but got an error....
