Magento slow only on save (NGINX)

Question

Magento 1.9.2.2 is very slow on product save within an NGINX enviroment. I use following settings: PHP-FPM 5.6.8 / 5.6.2

Php.ini

memory_limit = 2048M
max_execution_time = 1800

upload_max_filesize = 100M
session.auto_start = off
suhosin.session.cryptua = off
zend.ze1_compatibility_mode = Off

apc.shm_size=1024M
apc.num_files_hint=10000
apc.user_entries_hint=10000
apc.max_file_size=5M
apc.stat=0
apc.optimization=0
apc.include_once_override=1
apc.ttl=48000
apc.user_ttl=48000

realpath_cache_size = 32k
realpath_cache_ttl = 7200
default_socket_timeout = 90
pdo_mysql.cache_size = 2000
output_buffering = 4096

It is very fast in frontend. But on save it is very slow.

Do you have any recommendations for a fix?

Answer 1

First your product save is primarily going to be dictated by the speed of you server and your MySQL server. Since you admin doesn't care if your pages are cached or not they still have to process the php so your response from the server is not going to be much different in Nginx or Apache.

You need to look for at how many CPU's you have in your server and the amount of RAM. Of course SSD helps and having a dedicated rather than a VPS will also help. You should consider replacing the standard MySQL server with Percona.

You "Very fast frontend" is a result of the static pages that Nginx is serving up, the fact that your Admin is not static and relies on the server itself tell me that you need to increase the size of your server.

Answer 2

I managed to bring down the save speed from about 30-45 seconds to only 3 by enabeling HHVM instead of PHP-FPM.

The only thing not working was the image upload button. This issue can be resolved with https://github.com/facebook/hhvm/issues/4993#issuecomment-79039837

Thanks for everybody supporting here.
