Zimbra is very slow today and keeps giving me the server is slow to respond errors in the GUI. I know this is a very general question but what can I do to troubleshoot. I have checked the zimbra.log and everything there seems fine what are the other logs i can check? Are there some test i can run? Is there a good bandwidth monitoring tool for fedora mabey someone one the server is hogging all the bandwidth? Not sure what to do just some pointers would be appriciated

thank you

ps I shutdown the server down last night for backup could things be out of sync now??
