> 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.
