看了下服务器后台的java进程,基本上都在睡眠,占用也就几十M.
主机、服务器是同一个局域网的，但是后台比较卡顿，比如加载插件页面至少7-10s。

快速添加一个bgm条目要三四十秒。

还有把条目标记为“在看”直接延迟报错，虽然等了十几秒后还是成功了。

条目拉取和收藏慢是因为要请求番组计划，拉取没办法，但是收藏更新后面可以想办法丢给事件监听异步处理

看了下服务器后台的java进程,基本上都在睡眠,占用也就几十M.
主机、服务器是同一个局域网的，但是后台比较卡顿，比如加载插件页面至少7-10s。

快速添加一个bgm条目要三四十秒。

还有把条目标记为“在看”直接延迟报错，虽然等了十几秒后还是成功了。

你确定内存占用才几十MB？我这边内存都占用了500多MB了

本地电脑

本地电脑是没有网络延迟的，必然不卡，单个Java运行的进程（应该就是IKAROS）16g内存占用600m commit size

600mb才是正常情况，java 程序就这点不好，内存占用很大。

期待以后能有个golang版本，我暂时就主要用本地版就行了。nas就尽量冷备份用，保护磁头延长寿命，小机器就不折腾了

Ikaros server肯定不止占用几十MB的内存

我是按大小排序的，旧的树莓派还跑操作系统呢。用惯DOCKER的富哥肯定无法想像普通老百姓的内存日常的。

用的是群晖系统，可能是垃圾回收机制比较激进。启动的时候Ikaros server会占用100+M，然后Ikaros server内存就被系统慢慢回收完了

不会用docker，建议可以试试1panel 安装 ikaros? 安装ikaros只需要点点点就行。

可以去网店弄个小工控机作为家里的主路由器，我目前用的就是N4500的工控机，装了PVE，虚拟机安装的OpenWRT和一台Ubuntu，ikaros安装在ubuntu里，然后用115网盘存视频，通过alist插件导入ikaros成为附件，弄好后可以直接播放番剧。

配置参数 | 说明 | 示例
-- | -- | --
-Xmx | 设置最大堆大小。 | -Xmx3550m，设置JVM最大可用内存为3550 MB。
-Xms | 设置JVM初始内存。 | -Xms3550m，设置JVM初始内存为3550 MB。此值建议与-Xmx相同，避免每次垃圾回收完成后JVM重新分配内存。
-Xmn | 设置年轻代大小。 | -Xmn2g，设置年轻代大小为2 GB。整个JVM内存大小=年轻代大小+年老代大小+持久代大小。持久代一般固定大小为64 MB，所以增大年轻代后，将会减小年老代大小。此值对系统性能影响较大，Sun官方推荐配置为整个堆的3/8。
-Xss | 设置线程的栈大小。 | -Xss128k，设置每个线程的栈大小为128 KB。说明JDK 5.0版本以后每个线程栈大小为1 MB，JDK 5.0以前版本每个线程栈大小为256 KB。请依据应用的线程所需内存大小进行调整。在相同物理内存下，减小该值可以生成更多的线程。但是操作系统对一个进程内的线程个数有一定的限制，无法无限生成，一般在3000个~5000个。
-XX:NewRatio=n | 设置年轻代和年老代的比值。 | -XX:NewRatio=4，设置年轻代（包括Eden和两个Survivor区）与年老代的比值（除去持久代）。如果设置为4，那么年轻代与年老代所占比值为1:4，年轻代占整个堆栈的1/5。
-XX:SurvivorRatio=n | 年轻代中Eden区与两个Survivor区的比值。 | -XX:SurvivorRatio=4，设置年轻代中Eden区与Survivor区的大小比值。如果设置为4，那么两个Survivor区与一个Eden区的比值为2:4，一个Survivor区占整个年轻代的1/6。
-XX:MaxPermSize=n | 设置持久代大小。 | -XX:MaxPermSize=16m，设置持久代大小为16 MB。
-XX:MaxTenuringThreshold=n | 设置垃圾最大年龄。 | -XX:MaxTenuringThreshold=0，设置垃圾最大年龄。如果设置为0，那么年轻代对象不经过Survivor区，直接进入年老代。对于年老代比较多的应用，提高了效率。如果将此值设置为较大值，那么年轻代对象会在Survivor区进行多次复制，增加了对象在年轻代的存活时间，增加在年轻代即被回收的概率。

您好，我再请教下，FLYWAY相关参数只是“第一次部署迁移数据库到POSTGRESQL”的时候用到，还是说部署迁移完以后，每次重启程序都需要添加（FLYWAY相关参数）、作为“持续的桥梁”？逻辑上来说，数据库迁移应当是一次性、永久性的。
