You can also force the replication by running below command and see if there is any errors.
repadmin /syncall /AdeP
You can also ran repadmin /replsum which will show the replication summary status.
You can also ran dcdiag /q to check for errors.

You can use repadmin to analyze replication

The AD team has a good blog with examples   http://blogs.technet.com/b/askds/archive/2009/07/01/getting-over-replmon.aspx

There is also a repadmin whitepaper you can find

repadmin /showrepl * to get you started

As far as performance

You can use collector sets, another good blog  http://blogs.technet.com/b/askds/archive/2010/06/08/son-of-spa-ad-data-collector-sets-in-win2008-and-beyond.aspx

If you want to take it to another level you can collect your own logs.  Now how do you analyze those logs if you don't do it every day.

There is the PAL tool written by a Microsoft PFE that can help   http://pal.codeplex.com/  it can help you with thresholds.  Take a look at the screenshot from my lab.  Again you would need to provide the log file.

With three DCs you probably won't have a lot of perf issues on a smaller network.  Make sure to have enough RAM to cache AD (ntds.dit)

Thanks
