Does this plugin cache redirections?

    I’ve been using ‘permalink finder’ plugin and it has a big unsolved problem. It does not cache the redirections. It looks like every time the plugin finds a 404 page error, it tries to find an alternative page to show, even if the same not-found page was redirected 100.000 times before to the same alternative page.

    This means that every redirection turns very slow every page load. Waiting times in my site jumps to 1.5-4 secs because there are thousands of pages to search.

    Does your plugin cache the redirections anyway to speed up the process?

    Hello,

    I try to keep this plugin as much lightweight as possible, which means that I don’t log events or save/read non-essential data in the databale. Therefore, there’s no “direct” redirection caching, unless you run on a opcode with database caching configuration.

    However, I strongly advise you to test it out, because most users point out it’s great speed performance.

    In fact, I was also using Permalink Finder on a server under heavy load (+100.000 hits a day), and decided to write my own solution because it did some uncessary things, like, multiple calls to DB before sending response. When I switched off, it definitely speeded up 404 response time, and for the same result.

    If you decide to try this plugin, can you please share your experience?

    Regards.

    I tested it.

    It’s better than ‘permalink finder’ for one reason: the non-404 error pages load very fast, just like if there were no plugin activated. With ‘permalink finder’ all pages load very slow, even the ones that don’t need to be redirected.

    Although your plugin still is as slow as ‘permalink finder’ redirecting.

    A simple table in the database storing the destination redirection pages would speed up the sites using your plugin a lot, only a suggestion.

    Hello,

    I’ll consider doing so after benchmarking a very busy website (with or without logging).

    Thanks for the suggestion!

    Regards.
