http://issues.apache.org/bugzilla/show_bug.cgi?id=33513 Summary: Unnecessary string object allocation in ConstantPoolGen Product: BCEL Version: unspecified Platform: PC URL: http://www.helsinki.fi/~pohjalai/BCEL-patch.diff OS/Version: All Status: NEW Severity: enhancement Priority: P2 Component: Main AssignedTo: bcel-dev@jakarta.apache.org ReportedBy: [EMAIL PROTECTED] I was writing software that uses the BCEL library. Having performance problems, I found out that generic/ConstantPoolGen.java does unnecessary StringBuffer expansion: in two cases the length of the resulting string is known beforehand, but the created StringBuffer is not given a starting length for the internal buffer. With the attached patch applied, the running time of my application decreased from 1 min 45 seconds to 1 min 30 seconds as the generation of new constant pools was faster. (However, by rewriting my algorithm to do less constant pool instantiations, the running time dropped to 25 seconds). -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
