How to speed up IntelliJ on Mac OS X 10.9

I'm using Mac OSX 10.9 and Intellij Idea 13 on a decked out machine (7i processor, 16GB RAM, 64 bit, etc.). I have things working well; however, it seems to me that Intellij is running pretty slow (approx. 5 mins to boot up, almost a full 2 minutes to compile a system out print line class, etc.). As a frame of reference I have looked through numerous posts and have landed on the configurations below. My question is this. Does anyone else use a similar set up and have it running quicker? If so, what modifications have you made to your environment to speed things up. Thanks in advance for any help.

Java Version:

Switched from jdk1.6 to jdk1.7

idea.vmoptions:

-ea
-server
-Xms1g
-Xmx1g
-Xss16m
-XX:PermSize=512m
-XX:MaxPermSize=512m
-XX:+DoEscapeAnalysis
-XX:+UseCompressedOops
-XX:+UnlockExperimentalVMOptions
-XX:+UseConcMarkSweepGC
-XX:LargePageSizeInBytes=256m
-XX:ReservedCodeCacheSize=96m
-XX:+UseCodeCacheFlushing
-XX:+UseCompressedOops
-XX:ParallelGCThreads=8
-XX:+UseParNewGC
-XX:+UseConcMarkSweepGC
-XX:+DisableExplicitGC
-XX:+ExplicitGCInvokesConcurrent
-XX:+PrintGCDetails
-XX:+PrintFlagsFinal
-XX:+AggressiveOpts
-XX:+HeapDumpOnOutOfMemoryError
-XX:+CMSClassUnloadingEnabled
-XX:+CMSPermGenSweepingEnabled
-XX:CMSInitiatingOccupancyFraction=60
-XX:+CMSClassUnloadingEnabled
-XX:+CMSParallelRemarkEnabled
-XX:+UseAdaptiveGCBoundary
-XX:+UseSplitVerifier
-XX:CompileThreshold=10000
-XX:+UseCompressedStrings
-XX:+OptimizeStringConcat
-XX:+UseStringCache
-XX:+UseFastAccessorMethods
-XX:+UnlockDiagnosticVMOptions

info.plist (modification):

<key>LSArchitecturePriority</key>
<array>
  <string>x86_64</string>
</array>

  <key>JVMVersion</key>
  <string>1.7*</string>

Here's the scoop. There is a lot of stuff out there about changing the heap size, garbage collectors and what not. It may not be the root cause of your problem. Be sure to understand what you are setting in your vmoptions file as several suggestions aren't really supported any longer. I worked with the folks at IntelliJ going back and forth with log files and what not and it boils down to this. Check your anti virus. After adjusting my anti-virus, the following settings have IntelliJ screaming. Please note that this was the cause to my individual problem; so be sure to check your log files because that is where I started to find answers.

JDK 1.6

.vmoptions is running in the /Application/IntelliJ13/bin:

-Xms128m
-Xmx750m
-XX:MaxPermSize=350m
-XX:ReservedCodeCacheSize=96m
-XX:+UseCompressedOops

*notice that you don't need to allocate huge amounts of system resources. If you set up your system correctly it isn't needed.

Idea.plist:

<key>LSArchitecturePriority</key>
<array>
  <string>x86_64</string>
  <string>i386</string>
</array>

<key>JVMVersion</key>
<string>1.6*</string>

I know it is simple but it works.

I strongly suggest you not to use all these VM options (especially those controlling garbage collector) unless you actually measure they will improve performance. Please report reproducable performance problems as described here https://intellij-support.jetbrains.com/entries/29983118-Reporting-performance-problems
