I have a fresh install of Roundcube on a Ubuntu 16.04 server with Apache2, php7 and mysql-server 5.7. It takes alot of time to login and load pages(more than 10 seconds) and the server seems to have enough free RAM and CPU is barely used. I tried to use memcache but no change. I also enabled imap_debug as seen on other posts, but i don't see anything wrong (i attached a file with some imap logs).
Does anyone have any idea how to make roundcube faster?
Thanks.
