  • How To Start A Chat Plugin After The Page Has Fully Loaded
    Not heard of, I mainly use lighthouse, screamingfrog and CRUX data :D. - Source: Reddit / 12 days ago
  • Scaling a web application which is growing very fast
    Do you have XP with alternatives to It may helps, but sounds a little expensive for evaluating performance issues. I found also MySQLTuner which is free (of course it only helps with the database). - Source: Reddit / 2 months ago
  • Scaling a web application which is growing very fast
    Go get a subscription to and profile your application. I guarantee you that your queries to the DB are shit and not using indices. Redis will just mask the issue. You probably also have a bunch of PHP code being ran in loops. - Source: Reddit / 2 months ago
  • Making sure your website won't crash again
    Although the connection with the API should no longer cause the trouble, we knew that this was the most compute-heavy part of the platform. So the fewer requests are sent to that API, the better the website performance would be. We used to check how often the web app uses the API and we got interesting results. We noticed that the homepage, the most frequently visited page, used the API twice per each... - Source: / 9 months ago
  • Guide to install xhprof (profiling) in wordpress to debug slow php
    Nice article; skimming over it, it seems exhaustive and well-written. But nowadays, I'd generally recommend over XHProf. Yes, it's a (mostly) closed source SAAS platform, and the free tier only offers the most absolutely basic of tools, but by the time performance really starts to matter on your wordpress site, I don't think ~$30 a month is a dealbreaker. Installation is easier, the visualisation... - Source: Reddit / 10 months ago
  • Strangler Pattern in practice
    The problems were like with any legacy application. It was necessary to patch urgent bugs and optimize the code in some parts. We mainly used Blackfire and MySQL Slow Query Log to monitor and look for the causes of problems. - Source: / 12 months ago
  • Automated Scaling Suggestions
    Optimizing should be done immediately though. Use for the PHP portion of optimizing, and then for the database use Percona MySQL. In addition to that use Percona MySQL Monitoring and Management (PMM) for the database. A single shitty query can nuke your database and "optimizing" the site may even be done in minutes compared to days spent on scaling. - Source: Reddit / about 1 year ago
  • Free for dev - list of software (SaaS, PaaS, IaaS, etc.) — Blackfire is the SaaS-delivered Application Performance Solution. Free Hacker plan (PHP only). - Source: / over 1 year ago
  • How to analyse XDebug profile in QCachegrind to find performance bottlenecks ?
    Yes, I had tried other tools(, tideways) which use to tell me that there is problem with `apply_filters` and `do_action` which makes more sense they are the function which actually help customize everything inside wp. - Source: Reddit / almost 2 years ago
  • High TTFB - running out of ideas to try
    If it's way lower, start profiling your code (try - Source: Reddit / about 2 years ago
  • Don't blindly trust profilers
    I recently encountered an interesting case. I was trying to optimize the MessagePack unpacking, but after testing the performance of the new faster (as I thought) version, it turned out to be slower than the original implementation. Trying to figure out which part of the code was causing the slowdown, I reran the tests with Blackfire and was surprised to see that the profiler reported a 30% improvement in the new... - Source: Reddit / about 2 years ago
