If you think it's valuable to track latency, that seems like something you could just do. Grab the logfiles process them in your home directory, produce some graphs, keep the data over time and track changes. Ideally it would be done centrally, but as a starting point just do it yourself. Not having a dev / test / qa environment is inexcusable, why do you not have that? Why can't you just set one up yourself? Possibly on your own workstation or some VMs, just find a way to do it. Linter warnings are of highly variable quality. Don't bother about anything stylistic - tabs vs spaces, camel case vs underscores - those things never caused anyone's software to not work. Ask yourself "could this break something in production?". If the answer is yes, then create a code change to fix one instance of the problem and submit it for review (not every instance of every problem, just one instance of one specific problem that could affect production). People will ask why it's a problem, you can explain it, and if you've selected a good example of a non-trivial problem, they'll accept it and merge it. Then, go and find the other instances of the same problem after you have set the precedent, and there will be less resistance. Then, start working on other problems, rinse and repeat. Doing this will educate people along the way, and will work better than some big shock-and-awe change that touches a lot of things at once. Go easy on criticizing other people's work during code review, they're often emotionally attached to their code at that point since it's the last step in something they've been working on for weeks and want to move on from. Again, only raise things in other peoples code that could break things in production. As for accepting things and letting go, I'd say it's more a question of picking your battles. Don't accept everything and let go. Try to improve things to the extent you can while you are there, even if that isn't forever.
