I like how easy it was to install percoanxa cluster with just one click! It's really fast for me as well since i'm not using any heavy queries or anything else so my experience has been great till now but if you are looking forward having more features then go ahead otherwise its pretty much good enought right? Not sure about this yet because we haven't used all functions fully which will be released later by them after they have tested us thoroughly!! So far everything works fine though no issues atleast nothing majorly bad either! We use pxc mainly when our website goes down due too many users visiting simultaneously sometimes there may some minor slowdowns here nthere depending upon traffic load however overall very stable system!!
