Magento2 Runs Slow - Developer Mode.

[tapansoda]

I have installed Magento2 and have discovered running slow in developer mode. It takes around 8-10 seconds to load pages completely, with all cache types enabled. Below are more specific details in regards to the software stack that I have.

Operating System :- Ubuntu 14.04.3 LTS - 64 Bit
Processor:- Intel CORE I5 3rd Generation
RAM :- 8 GB (1X8) DDR3 1333MHZ
PHP Version:- 5.5.9
Apache Version:- 2.4.7
MySQL Version:- 5.6.27

1. I would like to understand what should be an ideal page load time for Magento2 in developer mode?

2. The software stack that I have mentioned above looks to meet the recommendation, although if there are any improvements that can be made then kindly highlight those.

3. Is there any specific practice that should be followed while working in M2 developer mode? Examples of such specific practice can be in regards to client-side less compilation OR any other factor that may affect the load time.

4. In general it is a good practice to have cache disabled during development, however having cache disabled looks to be a real pain with Magento2, it loads way slow around 30 seconds with cache disabled. Any suggestions?

Thanks,
Tapan

No solution but restarting the mysql service in regular base have increased my systems performance a lot.

Is it time to first byte or page with all assets loaded in browser?

Normal page load time is less than a second. Usual reasons for slow page generation are xdebug debugging session, xdebug profiler, opcache turned off.

Restarting MySQL improves performance? I wonder if you are running out of memory and thrashing your machine. I am running Apache + php 7 + MySQL in a docker container within virtual box on my laptop and after first generation of a page most pages come back sub-second,

                                                                                  Did you say sub-second? Does this include category and product detail pages? And in developer-mode?

@alankent - Do you think we require any changes with the software stack that I have pointed out above? We are not using docker container with virtual box, is that recommended? If we disable cache it takes around 20-30secs for page to load? If we enable cache it works fast say 6-8 secs, but as far as I understand it is recommended to have cache disable in development mode to view the changes made.

You have mentioned after first generation of a page most pages come back sub-second - I believe you are getting sub-second due to browser cache, you can clear your browser cache and test it. Are you still getting that page in sub-second? If yes, can you please help us out of what maybe going wrong on our side.

[alankent]

I do not believe the pages are not cached in the web browser - they change when I fiddle with the server code. Also browser cached pages I would expect to be even faster.
Could you check your paging rates? I am wondering if 8GB is sufficient memory.
If that does not work, there is something I would be curious if I can get you to try if you have the time - please drop me an email at akent at magento.com and I will email instructions.

[tapansoda]

@alankent appreciate for your prompt response.

I am on Ubuntu 14.04.3 LTS - 64 Bit, what is the best way to check for paging rates? I will send you the output for the same.

Also I have send you an email just in case it its not a problem with paging rates. You can send me instructions on that email id.

Thanks,
Tapan

It is extremely slow on my vagrant despite having a $8000 computer and devoting lots of resources to my vagrant and php. Of course every time this question is asked people assume its for live and tell them to enable caching but this does not help while developing/theming. Infact magneto 1 is much faster on my local vagrant at work on a much worse computer to develop in. Its just impossible.

When Magento 2 first release, i tried a fresh install and it was amazingly fast. Now after a while, Magetno 2.1 came out and i make a new fresh site, this time is is painfully slow. My local machine is quite good, best Ivy Core with 8GB Ram. If I upload this site to my remote server, it takes like 30 seconds to load homepage. I have read many threads about this slow issue and no one seem to understand why. Please don't tell me to enable cache or merge css,jss, as i need to work in dev mode.
What's wrong with Magento 2 and their dev team? No one figure out why?

[piotrekkaminski]

@maconeto what PHP version? do you have opcode cache enabled? btw internal developers usually work with all caches enabled and flush the cache as needed.

[maconeto]

PHP version 5.6.
I don't enable any kind of cache. My idea is that Magento should not be that slow even without cache. It is not reasonable. A month or two ago i tried an eariler version and it was fast, installed on the same machine, same environment. If it loads 10 - 30 seconds on local, it must be something else rather than just cache. It goes from amazingly fast to terribly slow.

Hi!

Any news about this?

Reloading a page in any web project in development (so without cache) should not be too slow. It's time consuming.
