D28521: Use more UDSEntry::reserve() calls to avoid reallocs on multiple inserts

[Friedrich W. H. Kossebau]

kossebau added a comment.


  Looking at kio-extras, seems there are quite some more cases where the number of values inserted is fixed.
  
  Okay, I will revive my std::initializer_list code again, in a separate patch, there are enough use-cases available, so at least the sugar code is nice to have, even without measurable performance changes. Perhaps one of the reviewers then will be able to help how to do efficient code which avoids the unneeded QString constructor/destructor calls.
  
  Until then, the current patch should at least do some µ-improvement for people browsing lots of files via ftp & http :)
