Troubleshooting SDP not starting all the way

I have been reading performance turning guides for SDP, PGSQL, and JVM to get SDP to start faster... it was taking almost 5 minutes. I got it down to under 3 minutes but now run.bat never finishes; the batch file just hangs. If I log off the ticket system will go down. Does anyone have any idea how to troubleshoot this? Or should I just set it all back?

wrapper.conf changes:

# Initial Java Heap Size (in MB)

wrapper.java.initmemory=2048

# Maximum Java Heap Size (in MB)

wrapper.java.maxmemory=4096

Changes to run.bat

set JAVA_OPTS=%JAVA_OPTS% -Xms2G -Xmx4G -XX:+UseG1GC -XX:MaxGCPauseMillis=200 -XX:ParallelGCThreads=20 -XX:ConcGCThreads=5 -XX:InitiatingHeapOccupancyPercent=70 -Dsdp.java.gc=false

Changes to postgres_ext.conf

shared_buffers = 2GB

effective_cache_size = 6GB

maintenance_work_mem = 256MB

work_mem = 48MB

wal_buffers = 16MB

Thanks in Advance
