Yes, my server and DNS crashed and this caused “some” issues. Luckily I was able to recover everything pretty fast – it should be working now. ??

Yes, that makes sense. ??

I will look, latest version was a minor fix. ?? i think readme was in the text file..

what is the difference between first and second benchmark on your screenshot? Is database server local? Can it be, that you have it on CloudLinux with database throttling enabled?

Hello,

yes, i can confirm – same here with W3 Total Cache.. It used to work before, when you enable “Enable caching for wp-admin requests” – but it is not working anymore. What can I say…. My plugin is purely using WordPress object cache functions – so it comes down to plugins, that are responsible for this functionality.

Unfortunately I don’t think I can help with this. My logic for these tests is that – plugin sets small value in the beginning and tries to read it later. If value is not being received from the cache later – plugin considers, that object cache is not working, as expected.

As you can see – it is working fine with Redis Object cache plugin from Till Kruss.

sure, any time!

Unfortunately I could not reproduce it – at least with my setup, on servers where I have redis – it just works.. To test, if Redis is working at all – plugin stores one small value inside the object cache. Later, after few benchmarks – it tries to read that small value back. If value is missing – plugin considers, that object cache is not working as it should and do not try to benchmark it at all..

Well, this sounds like an issue on your WordPress – try to remove plugin folder – by default it is :

wp-content/plugins/wpbenchmark

You are welcome! ??

Thanks for the info. ??

Very strange, if object cache would not work – you would not get results for other sub-tests. Do you have enough memory and limits on reading and for PHP? And for object cache – so you are using Till Kruss’ plugin, right?

Sorry for delay – was it working before with the same config? What plugin do you use for object caching?

Sorry for a delay. Well, it might mean, that your hosting has IO limitations. Technically for most times you won’t feel it. Still the most important part is CPU, which looks quite OK for you. ??

To test, if object cache is working – plugin will set small value at the beginning of the benchmark execution. Later, when it gets to object cache test routines – it will try to read that value. If value does not exist – plugin will make a conclusion, that object cache is not working correctly.

For me it is impossible to say, why quite often it fails – but to be honest – I think something somewhere is not working as it should, unless my assumptions are wrong.. Object caching with Redis is tricky on shared hosting, except when you have a dedicated Redis (e..g through containers). Docket cache is not so bad, but as it uses filesystem – it’s not that fast.

My personal opinion about object cache is quite doubtful – I haven’t see significant improvements with it, at least not on small sites.

Thanks for the review and opinion.

Network latency, indeed, can be an issue. And yes, number of queries, that plugin executes is enormous – just because our servers are too fast and obviously because so far I did not come across a good and heavy and slow SQL query – but I am open for that.

I wonder what queries would look more realistic? Once again – very open for suggestions.

And when it comes to scoring – yes, the score number depends on some values, stored on my server, but it does not depend on how many benchmark tests have been performed. I have measured performance of a very fast server and those timings serve as a reference. What ever score you’ve got – does not interfere anyone. And regarding more details – you can see actual time spent for each test on a detailed page. ??

Indeed, figuring out database server bottleneck is not an easy task. Especially if you know, that you have a good hardware – it would then come to the fact of logging all SQL queries and analyzing those. Purpose of this plugin was more to identify and compare different servers, different hosting platforms to see how the perform and if the hardware is “ok” or not – because for those, who are usually on the shared hosting subscriptions – that part is a totally dark box.

Take care!:)
