I am using SIAPI in my custom search application for IBM Content Analytics with Enterprise Search.
But it seems to take 30 seconds or more to obtain a searchable object.
This was not a problem when I used the same SIAPI code with OmniFind.
The property "httpVersion" in SIAPI was "1.0" by default, but "1.1" is faster.
Resolving the problem
If you are using the default SIAPI sample application, edit "api.properties" in the sample directory, and change from:
"httpVersion=1.0" to "httpVersion=1.1"
