             Summary: Limit number of user threads
                 Key: JCLOUDS-459
                 URL: https://issues.apache.org/jira/browse/JCLOUDS-459
             Project: jclouds
          Issue Type: Improvement
          Components: jclouds-core
    Affects Versions: 1.7.1
            Reporter: Andrew Gaul


Presently jclouds does not limit the number of user threads.  While 
de-asyncification could address this in the long-term, in the short-term we 
should protect our users with some sane default.  I suggest 20 or 50, the 
former mirroring the number of IO threads, and the latter sourced from my 
extensive testing of most blobstore providers.  Note that Atmos providers have 
issues with large numbers of concurrent requests and errors from JCLOUDS-137 
will occur.  I work around these in my application by setting 10 IO and 10 user 
threads for Atmos Online and 8 and 8 for Synaptic Atmos.
