我这里主要存zabbix监控信息，使用了一个存储组，每1分钟存2000条时序数据，我应该调整哪些内存参数？我现在使用1台4核16G机器。
我修改了iotdb-env.sh中的配置：
half_system_memory_in_mb=`expr $system_memory_in_mb / 2`
quarter_system_memory_in_mb=`expr $half_system_memory_in_mb / 2`
if [ "$half_system_memory_in_mb" -gt "1024" ]
then
half_system_memory_in_mb="4096"
fi
if [ "$quarter_system_memory_in_mb" -gt "8192" ]
then
quarter_system_memory_in_mb="8192"
fi
if [ "$half_system_memory_in_mb" -gt "$quarter_system_memory_in_mb" ]
then
max_heap_size_in_mb="$half_system_memory_in_mb"
else
max_heap_size_in_mb="$quarter_system_memory_in_mb"
fi
MAX_HEAP_SIZE="${max_heap_size_in_mb}M"
# Young gen: min(max_sensible_per_modern_cpu_core * num_cores, 1/4 *
heap size)
max_sensible_yg_per_core_in_mb="200"
max_sensible_yg_in_mb=`expr $max_sensible_yg_per_core_in_mb "*"
$system_cpu_cores`
desired_yg_in_mb=`expr $max_heap_size_in_mb / 4`
if [ "$desired_yg_in_mb" -gt "$max_sensible_yg_in_mb" ]
then
HEAP_NEWSIZE="${max_sensible_yg_in_mb}M"
else
HEAP_NEWSIZE="${desired_yg_in_mb}M"
fi
请问这个问题如何解决？
