Tips for improving Forge performance?

While playing abnormally long games on Forge where many cards are on the battlefield (at least more than 10 I'd guess), I notice long delays between phases/interrupts/etc.

I'm unable to locate minimum system requirements for Forge but am quite certain that my computer *should* be able to run it rather well. Some specs if it helps:

Code: Select all: Java Version: 6 update 24 (build 1.6.0_24-b07) // OS Name Microsoft Windows 7 Ultimate 32-bit System Manufacturer Hewlett-Packard System Model Compaq Presario CQ50 Notebook PC System Type X86-based PC Processor Intel(R) Pentium(R) Dual CPU T3200 @ 2.00GHz, 2000 Mhz, 2 Core(s), 2 Logical Processor(s) Installed Physical Memory (RAM) 2.00 GB Total Physical Memory 1.93 GB Available Physical Memory 1.06 GB Total Virtual Memory 3.87 GB Available Virtual Memory 2.51 GB Page File Space 1.93 GB Page File C:\pagefile.sys // GFX Card: Name Mobile Intel(R) 4 Series Express Chipset Family Adapter Type Mobile Intel(R) 4 Series Express Chipset Family, Intel Corporation compatible Adapter Description Mobile Intel(R) 4 Series Express Chipset Family Adapter RAM 797.60 MB (836,341,760 bytes) Installed Drivers igdumdx32.dll,igd10umd32.dll Driver Version 8.15.10.2281 Color Table Entries 4294967296 Resolution 1280 x 800 x 60 hertz Bits/Pixel 32 Driver c:\windows\system32\drivers\igdkmd32.sys (8.15.10.2281, 8.62 MB (9,035,776 bytes), 3/11/2011 4:28 PM)

Thanks for any help ahead of time!

You may be able to squeeze a little bit of performance by tweaking the java command line parameters (don't expect much just a bit here and there).

Code: Select all: java -Xmn128M -Xms1024M -Xmx1024M -XX:+UseConcMarkSweepGC -XX:+UseAdaptiveSizePolicy -XX:CompileThreshold=100 -XX:+UseParNewGC -jar forge.jar

Some of these might already be default values depending on your java version. The rest of the performance can only be gained by improving the code.

Braids is working on a few things that should cut down on how much memory Forge uses. There's a topic on how to get the version currently on the SVN. The revision currently in place already has some of that work incorporated.
