REM Default parameters for a basic server.
REM ======== Optimize memory settings =======
REM Minimal size with geodata is 1.5G, w/o geo 1G
REM Make sure -Xmn value is always 1/4 the size of -Xms and -Xmx.
REM -Xms<size> set initial Java heap size
REM -Xmx<size> set maximum Java heap size
REM -Xmn<size> Size of young generation
REM ===============================
REM Set heap min/max to same size for consistent results
REM одинаковый размер памяти для Xms и Xmx, JVM пытается удержать размер heap'а минимальным, и если его нужно меньше, чем в Xmx - гоняет GC понапрасну
SET java_opts=%java_opts% -Xms2048m
SET java_opts=%java_opts% -Xmx2048m
REM Non Heap memory
SET java_opts=%java_opts% -XX:PermSize=512m
REM Maximum size of the permanent generation.

REM Default size of new generation

REM instructs the VM to set a 2:1 ratio between young and tenured generations (Ratio of new/old generation sizes)
REM SET java_opts=%java_opts% -XX:NewRatio=2
REM Sets survivor space ratio to 1:8, resulting in larger survivor spaces (the smaller the ratio, the larger the space). Larger survivor spaces allow short lived objects a longer time period to die in the young generation
REM SET java_opts=%java_opts% -XX:SurvivorRatio=8
REM Allows 80% of the survivor spaces to be occupied instead of the default 50%, allowing better utilization of the survivor space memory.
