IB's new build is incredibly slow

I just received this in an email from IB:

--------------------------------------------

"Dear Client,

You are receiving this communication as we have identified your account xxxxxxxxxx as one that is submitting orders via an API (either your own software or third party application) and using a TWS version that is substantially outdated and scheduled to be decommissioned for API purposes effective May 1, 2014.

Effective May 1, 2014, TWS versions below 940.0 will no longer be operable for API use, but will remain operable for non-API generated orders. It’s important to note that if you are integrating a third party software application (charting, order entry, analytical, etc.) with the TWS, you are doing so through the API and must upgrade if you wish to continue using that application.

To repeat, if you are receiving this notice and intend to continue using an API for order submission, you must upgrade your TWS version and the deadline for doing so is prior to May 1, 2014.

Should you have any questions regarding this matter, please contact your local Customer Service Center.

Technical Service Team"

----------------------------------------

This is crazy. We're less than a week away and the upgrade version is completely inoperable. DST- you guys need to push this decommissioning back by a month (at least).

Latest TWS is 944 (as you can see from the page you linked above); you can use your ancient API, you simply need to use newer TWS in conjunction with it.

Our support team is already working with jtrader33 to make sure there are no issues related to upgrade of his setup. If anyone has any issues - please don't hesitate to reach out to our customer support, see info on our website.
 
1. Why is it that so many of us never received a proper advance notice until today?

2. Looks like your partners were also just notified about this HUGE impact change and given virtually no real notice: http://www.ninjatrader.com/support/forum/showthread.php?t=65602

3. You released a stable "time-tested version of TWS" ver 939.4 on April 23, that's yesterday, and you're saying that 2 business days from now it will be unusable for API orders?

my point exactly. we all are forced to use latest possible. like it or not.stable or not
 
An update for anyone affected by the upgrade: If anything else goes wrong I will update the thread, but it looks like 944.3 is running fine for me now. It was a simple settings issue - essentially, the java options need to be set at this size -Xmx1024M -XX:MaxPermSize=256M. You can check those in the TWS shortcut under Properties -> Target. It's the same spot where you have to change System32 to sysWOW64 to avoid getting the ddedll.dll error message.

I will give dst and his group credit - it sounds like this was thrust on them and they were very responsive with emails, calls, etc. in getting this sorted out.


dst- I know you're probably quite busy with the migration, but at some point when you have time can you comment on whether TWS will ever be able to run on 64-bit java? I run my stuff on 64-bit across several machines, so it would be nice to only have one Java version installed and not deal with the System32/sysWOW64 changes everywhere when there's a TWS upgrade.

I'm running TWS since long time on 64-bit Java. Didn't install the 32-bit Java runtime version. Works well for me in combination with NinjaTrader7.
I'm missing something ?
