Dear Percona community,
I have heard a lot that Percona is the new way to go on open source db servers. I have a small VPS - 4core CPU; 4GB RAM and SSD on 64bit Debian 7.5 with Plesk 12.5 and MySQL 5.5.5. on stock(out of the box) settings. I have one slow WordPress website with bbPress on it right now. I want to squeeze out everything I can in order to speed up. I have three broad questions. The question number one is - will it be safe to upgrade to Percona 5.7? And the second question is how to do it? The third one - in my situation, will it be a noticeable upgrade in terms of database speed?
I have searched the web for tutorials but none of those I have found really fits my actual stack - Debian 7.5+Plesk 12.5. I just recently started to learn about the server administration for my own VPS.
