I keep reading that I should set the JVM parameters for Catalina in my Catalina.sh file. I am running Tomcat 8 as a Windows service. There is no Catalina.sh file. I tried adding JVM optimizations to System environment variable CATALINA_OPTS but I don't see it having any effect. The Tomcat log file indicates the same default Xms and Xmx (and other) parameters. Or are these the Tomcat parameters (for Tomcat itself) and not the parameters for my geoserver application?
Here is what I put in the global Environment strings in Windows:
CATALINA_OPTS=-server -Xmx512m -Xms48m XX:SoftRefLRUPolicyMSPerMB=36000 -XX:MaxPermSize=128m -XX+UseParallelGC
And here is what my log says:

Well, I gleaned this information from many different posts. There are several "answers" out there, but I only found one that actually worked.
First of all, if you are running Tomcat 8.0 as a service in the Windows OS, those BAT files (catalina.bat, setenv.bat if you created one) do not seem to be relevant at all. There are many who say "edit catalina.bat" or "add such and such to your setenv.bat file in the Tomcat bin folder", or "add CATALINA_OPTS environment variable with JVM parameters you want to use". None of these things have any effect on the Geoserver web app running in Tomcat 8, at least when it is running as a Windows service.
So, how do you tune/configure your JVM when running Tomcat 8.0 as a service? Assuming you "Installed" Tomcat 8.0 using the Windows Installer, go to your program menu and find the "Configure Tomcat" program. It brings up a properties window that looks as seen below. Use the Java tab. There is a field called "Java Options". Put all but the Xmx and Xms settings, as there are special fields below the Java Options field for these two values. So I added the following options:
These are exactly as recommended values from the Geoserver documentation regarding Container Considerations (see here: http://docs.geoserver.org/stable/en/user/production/container.html)
I'm currently running 32bit Tomcat 8.0 and 32bit JRE7 because the ImageIO native features documented by Geoserver are only available in 32bit. So I'm limited in how much of my machine's 8GB of RAM I can give to the jvm running Geoserver.
I'm not sure I'm actually using them (the native ImageIO dlls), though, and will consider upgrading everything to 64bit, so I can give the JVM even more memory. But because I am using 32bit, I found the following "Initial memory pool" and "Maximum memory pool" settings worked, and are working well:
It seems you must be careful what values you put in these fields. I'm using multiples of 512m. When I tried initial memory pool of 768m, Tomcat service would not start. If anyone can help clarify what the valid values for these fields are, feel free to add a comment to this answer. It was trial and error, and very frustrating to change an initial memory field to something that seemed reasonable, and this would cause the service to simply fail to start entirely. Found this in a log file: Error 4. Thanks for that explanation...
So here is what the config should look like. All the Java Options below the ones I added are exactly what were there already from the Tomcat installation:
Now when I logon to Geoserver's admin and select Server Status, I can see the following: JAI Maximum Memory 682 MB. JAI max memory is set to 50%, so this means there is 1364m available. I'm assuming the rest is Permgen or stack space, or some other use of memory. The default Tomcat settings provide a lot less than that (initial memory of 128m and max of 256m).
So far, it is running very well, all of the out of memory (Permgen) errors and other out of memory errors I've been trying to resolve no longer occur. The geoserver webapp also loads 30-40% faster than it did when it had a lot less memory.
