Improving IDEA 14 Ultimate Performance?

Is there something I can do to improve the overall performance of my IDEA 14 Ultimate installation? Everything seems slow and sluggish compared to Eclipse Luna in the same machine. Of course, IDEA probably does more for the improved user experience so I might not expect equal performance, but... Anyways, here's my specs:

Core i7-2630QM @ 2 GHz 6GB RAM

Windows 7 x64 Ultimate

W7 Hardware Performance Index:

CPU: 7.4
RAM: 7.4
GPU/Desktop: 5.6
GPU/Games: 6.2
HDD: 5.9

JDK/JRE 1.8 x64 (no other Javas installed)

IDEA_JDK_64
C:\Java\jdk\x64\1.8

JAVA_HOME
C:\Java\jdk\x64\1.8

JDK_HOME
C:\Java\jdk\x64\1.8

JRE_HOME
C:\Java\jre\x64\1.8

Running idea64.exe with:

-Xms256m
-Xmx750m
-XX:MaxPermSize=350m
-XX:ReservedCodeCacheSize=225m
-ea
-Dsun.io.useCanonCaches=false
-Djava.net.preferIPv4Stack=true
-Djsse.enableSNIExtension=false
-XX:+UseConcMarkSweepGC
-XX:SoftRefLRUPolicyMSPerMB=50

Or maybe my laptop just isn't up to running this IDE properly... Thanks in advance for any advice/suggestions.
