Linux内测版

比特彗星(BitComet)
356

docker是这样的，进程运行在宿主机上会被oom，目前Linux版本不支持sendfile调用操作系统缓存，而且预留默认值50MB空闲特别保守，没swap的情况下容易被杀进程，建议修改一下磁盘缓存上限

注：如果要修改配置文件请先停止容器，修改完成后在启动，这样才能修改成功
BitComet.xml 推荐设置

注：v2.12.3版network.tcp_connection_timeout不起效果，会强制默认值为128秒超时，也就是说这个v2.12.3版本可以调整network.max_connecting_connections为750，后续修复了在改回60

比如1GB内存实际程序占用used 800MB以内比较合适。
也就是说，centos7下要控制used在75%，避免超过80%，超过容易被kill杀进程
1G内存的vps运行docker上可以设置如下，检测应用程序占用800MB内存就自动重启容器（容器化后额外内存开销可能要设置为700MB）

内存 ≤ 4GB 的vps服务器也可以把内存保留改为300MB（不过Linux版本这个选项当前版本也没起效果，配置文件有效，但是实际上磁盘缓存没有进行下降）
