Subject [jira] Created: (HTTPCLIENT-895) Log creation impairs performance

Log creation impairs performance

                 Key: HTTPCLIENT-895
                 URL: https://issues.apache.org/jira/browse/HTTPCLIENT-895
             Project: HttpComponents HttpClient
          Issue Type: Improvement
          Components: HttpClient
    Affects Versions: 4.0 Final
            Reporter: Tony Poppleton
            Priority: Minor

Running JProfiler on a program that uses HttpClient with a ThreadSafeClientConnManager, revealed
that 5% of the time was spent constructing Log instances in class ClientParamsStack.

Oleg did some further investigation and found that DefaultRequestDirector also has the same

A simple solution would be to make the Log a static member variable, and do this on all classes
for consistency.  However this might not be the best solution for interoperating with some
frameworks (see http://wiki.apache.org/jakarta-commons/Logging/StaticLog)

Another solution would be to simply remove the Log from the affected classes, although they
are presumably there for a reason...
