Martin Tzvetanov Grigorov updated WICKET-6824: ---------------------------------------------- Fix Version/s: 8.10.0 > Use concatenation instead of String.format for frequently called methods > ------------------------------------------------------------------------ > > Key: WICKET-6824 > URL: https://issues.apache.org/jira/browse/WICKET-6824 > Project: Wicket > Issue Type: Improvement > Components: wicket-core > Affects Versions: 9.0.0 > Reporter: Thomas Heigl > Assignee: Thomas Heigl > Priority: Minor > Fix For: 9.1.0, 8.10.0 > > Attachments: image-2020-08-30-20-34-57-261.png, > image-2020-08-30-20-35-04-970.png > > > Two usages of {{String.format}} frequently show up in my production profiler: > !image-2020-08-30-20-34-57-261.png! > !image-2020-08-30-20-35-04-970.png! > Both methods are potentially called dozens or even hundreds of times for > large pages. > {{String.format}} has horrible performance and should mostly be used for > generating error messages and debug information. For a detailed analysis see: > [https://redfin.engineering/java-string-concatenation-which-way-is-best-8f590a7d22a8] > We should replace {{String.format}} with simple concatenation in both > instances. -- This message was sent by Atlassian Jira (v8.3.4#803005)
