Getting worse performance with save_comments = 0 and enable_file_override = 1 about zendoptimizerplus HOT 7 CLOSED

hi Ricard,

Thank you for the post and good bechmarks :)

I've never worked with Symphony myself, but already got few reports, that it doesn't work properly with save_comments=0. This option disables saving/loading doc_coments that used in Symphony for some purpose.

enable_file_override=1 may make speedup or slowdown dependent on application. It speedups file_exists(), is_file() and is_readable() for files cached by O+, but makes them a bit slower for the others.

Thanks. Dmitry.

Hi Dimitry

Well, Symfony2 uses annotations /comments as one of the ways you can configure your application. There is a CLI command that converts these annotations / comments into plain PHP and of course with save_comments = 0, this just does not work as it is perfectly explained in your documentation. However, once the cache is warmed up, Symfony2 works perfectly :)

Regarding enable_file_override... well it might slow down the first request, but not the subsequents right? Symfony2 uses a lot of files and it may slow down autoload the first time, but not the following ones if I understand properly what you mean. Weird indeed! Any other guesses about what might be slowing down the HTTP responses?

I didn't get how you may change save_comments to 0 after warming the cache.
You probably work with save_comments=1

No. It may speedup or slowdown not only the first request, but every
request, because those functions are executed at run-time.

Sorry I may have not explained myself properly about how Symfony deals with annotations and how I did the test. What I did was to set save_comments to 1, warm the cache (annotations are read) set save_comments back to 0, reload apache config and execute ab (once the cache is warm, Symfony does not read annotations any more). So for HTTP requests save_comments was set to 0

But what might explain performance decrease is what you say about enable_file_override, specially if it happens at run time as you mention

Thanks for clarifying all this stuff

In case files were already saved with doc comments, the save_comments value
doesn't matter.
It's possible to disable comments loading (load_comments=0), but it would
break Symphony.
Anyway, save/load_comments are not suitable optimization a for Symphony.

Restarting Apache does not reset Zend Optimizer+? If not, how can this cache be restarted?

from zendoptimizerplus.

Of course, it resets O+.
