And I will try out this > (https://github.com/spiral/roadrunner). We are talking about a blackbox. The code is simple ? How long take's the sql query ? What do you use to access the database PDO or mysqli ? Y ou wrote java is faster. Your java code access the same database ? You wrote a few images ? Do you only show the images with <img src=""> or are you converting them for thumbnails etc. A long time ago there was a great presentation from Rasmus about PHP Performance. So a simple query on my Server's with mod_php and mysql takes 0.0001 to 0.0008 seconds. If the simple query takes 0.01 Second which looks fast but php have to wait for the DB. So there you can loose factor 100 in the req/sec. Why are you using fpm and not the mod_php part in apache ? OPcache is active ? There are a lot of parameters we don't know. If you benchmark your code with an easy microtime(true) call to see how long your script takes. If you store the data in a file when you run your benchmark you can maybe see if a code part is waiting for the database or something else. So that the bottleneck ist not php. So i would go through the code with microtime() an look what takes long and then go deepter. if the code is heavy and the result dosen't change or a refresh after 5 min is ok you can use the APCu cache or so on. If your code is super fast an still slow requests then you have to strace the apache process to see if there is something miss configured. So as a PHP developer we cann't accept that Java is faster :) BR/Torsten > Thanks. > > Deepak > "The greatness of a nation can be judged by the way its animals are > treated - Mahatma Gandhi" > > +91 73500 12833 > deicool@xxxxxxxxx > > Facebook: https://www.facebook.com/deicool > LinkedIn: www.linkedin.com/in/deicool > > "Plant a Tree, Go Green" > > Make In India : http://www.makeinindia.com/home > > > On Tue, Oct 26, 2021 at 5:15 PM Alex <al-php@xxxxxxx> wrote: > > Hi. > > > > On 26.10.21 11:53, Deepak Goel wrote: > > > Hello > > > > > > I have a very simple PHP application which I develop on Apache- > > Web-Server.
