Here a comment fom the TWS API release notes that may or may not be of help to those experiencing performance issues:
When TWS connects either to IB via the internet, or an API client
application, it creates Java-based sockets of a predetermined size.
If an API application intends to make historical data requests that
return more than 1000 bars, it is recommended that TWS be configured
to increase the sizes of the API socket buffer. This can be done
in the "settings.xml" file in the user's Jts directory.
It is important that TWS not be running when its settings.xml file
is manually modified. In the <SystemSettings> XML element,
the <apiSocketBufferSizes> elements can be used for this purpose.
Adding this line to the <SystemSettings> element in settings.xml
should suffice:
<apiSocketBufferSizes>500000</apiSocketBufferSizes>
