SuiteCRM is slow

Hi, I have installed SuiteCRM and after I import only the Account (more or less 36000) i have noticed that is very slow.
Are there any particular specs the server must have?
Currently my server is on a virtual machine with 18 GB of RAM and 6 CPU.

One thing that really made a huge difference to me was changing the memory. Other settings to change are

upload_max_filesize = 60M
max_execution_time = 200
post_max_size = 120M
Memory limit to 256M or higher
Max input time to a large number

Made it actually a usable product.

Ok, thanks.
Now it goes better.

You can tweak from SuiteCrm as well. Things like the number of items on list view, counter… check here for more info:

If you have your scheduler working, I will suggest to change the time the AOD index task runs. Make sure it runs at out-of-the-office hours. It’s always to monitor the PHP running instances to make sure non of them is a zombie task or left over from the scheduler. In my case the index was getting stuck and I had to manually stop it. At the end I created a scheduled task to kill all PHP instances at certain time in the morning to make sure system is good for the entire day.
