Subject [jira] [Comment Edited] (SOLR-13533) Code Cleanup - Performance

No worries.

 
{quote}My personal take on this though is that unless they are showing up in a profiler under
real load fixing these isn't worth it.
{quote}
Indeed, real situations with real load are the ones that should be looked at first.

 

I'm fully expecting some of these PR's to receive the response of "this is not a priority,
refused".

 

I'll offer them anyway though. Unless it takes people's time. Which reminds me, again, please
nobody review this on their working hours, on the time they would actually spend on features
for this or another project they could be getting paid for. I added that as clarification
again to the original post.

on personal time you could be working on something that makes you money or improves the product
for your feature personally.

have the time for.

> Code cleanup as suggested by static analysis tools. Will be done in my spare time.
> If someone reviews this, please also do not take up actual time from your work to do
that. I do not wish to take away from your working hours.

> These are simple, trivial things, that were probably overlooked or not even considered(which
isn't an accusation or something negative). But also stuff that the Java compiler/JIT won't
optimize on its own.
>  
> That's what static analysis tool are good for: picking stuff like that up.
>  
> I'm talking about Intellij's static code analysis. Facebook's "Infer" for Java. Google's
"errorprone", etc...
> These are the kinds of things that, frankly, for the people actually working on real
features, are very time consuming, not even part of the feature, and have a very low chance
of actually turning up a real performance issue.
> So I'm opting to have a look at the results of these tools and implementing the sensible
stuff and if something bigger pops up I'll make a separate ticket for those things individually.
>  
> Creating this ticket so I can name a branch after it.
>  
> The only questions I have are: since the code base is so large, do I apply each subject
to all parts of it? Or only core? How do I split it up?
> Do I make multiple PRs with this one ticket? Or do I make multiple tickets and give each
their own PR?
