如果你没有公网IP请参考[这篇文章](https://forum.autonomys.xyz/t/ipv4-ipv6-node/4531/1) 方法很简单 在第一次同步缓存的时候可能很慢,完成同步可以要好几天 # Piece cache 简介 缓存是在farm的输出里面 如下部分 ```auto 2024-11-12T14:41:16.205619Z INFO subspace_farmer::farmer_cache: Piece cache sync 6.64% complete 2024-11-12T14:41:23.441913Z INFO subspace_farmer::farmer_cache: Piece cache sync 6.74% complete 2024-11-12T14:41:31.216118Z INFO subspace_farmer::farmer_cache: Piece cache sync 6.84% complete 2024-11-12T14:41:36.317267Z INFO subspace_farmer::farmer_cache: Piece cache sync 6.94% complete ``` 缓存的大小会越来越大,每次缓存变大就会有部分数据过期,同时重P,同时第一次绘制的时候也需要缓存来加速 ## 缓存的存储方法: 如果你是用的官方默认软件那么缓存会分割在每个你的地块部分 比如我有8个地块 缓存目前大小80个G 那么我每个地块的文件夹缓存部分可能存有10个G左右 如果你用的是官方的集群 那么缓存就是统一放在你指定的一个文件夹里面,这里的缓存你可以直接复制给别人用,非常方便 # 缓存加速方法 目前的加速方法就是通过连接数来找更多人拉取更多数据,更快 ```auto --in-connections 3000 ` --out-connections 3000 ` --pending-in-connections 3000 ` --pending-out-connections 3000 ` ``` 直接在farm启动的时候添加这4个参数 windows例子: ```auto .\farm farm ` --reward-address sug1MFpGUj5txtB43R2gyTWh7EyafZX4641SJ6KyZaMdgrmPJ ` --node-rpc-url ws://192.168.50.237:5845 ` --in-connections 3000 ` --out-connections 3000 ` --pending-in-connections 3000 ` --pending-out-connections 3000 ` path=D:\1,size=6.5Tib ` path=E:\1,size=6.5Tib ` path=F:\1,size=6.5Tib ` path=G:\1,size=6.5Tib ` path=H:\1,size=6.5Tib ` path=I:\1,size=6.5Tib ` path=J:\1,size=6.5Tib ` path=K:\1,size=6.5Tib ` path=L:\1,size=6.5Tib ` path=M:\1,size=6.5Tib ` path=N:\1,size=6.5Tib ` path=O:\1,size=6.5Tib ` ``` 在添加后,基本就可以全速下行拉取缓存了 ![image](https://canada1.discourse-cdn.com/flex011/uploads/subspace/original/2X/e/e7ad9f438dc21405b1c3cfe3fed22607f1f03c73.png) # 记住 缓存完毕后必须把这几个参数删除,或者调低,把3000改成30都可以或者就用官方默认的 如果不删除对路由器压力大,同时有运营商警告风险 删除后的启动参数例子 ```auto .\farm farm ` --reward-address sug1MFpGUj5txtB43R2gyTWh7EyafZX4641SJ6KyZaMdgrmPJ ` path=D:\1,size=6.5Tib path=E:\1,size=6.5Tib path=F:\1,size=6.5Tib path=G:\1,size=6.5Tib path=H:\1,size=6.5Tib path=I:\1,size=6.5Tib path=J:\1,size=6.5Tib path=K:\1,size=6.5Tib path=L:\1,size=6.5Tib path=M:\1,size=6.5Tib path=N:\1,size=6.5Tib path=O:\1,size=6.5Tib ``` # 在跑缓存的时候,如果上行过高,可以用路由器等工具限制一下上行 ![image](https://canada1.discourse-cdn.com/flex011/uploads/subspace/original/2X/d/de5d197e54906b00c1ca3b8d64ff30a7080f38f0.png) 因为我在测试中如果只拉in参数,设置下行连接数的时候,效果并不好,out和in的参数数量一致效果才是最好的 # 请一定在要缓存完毕后结束这个参数,不然对路由器非常不好 ---

I have reminded that this parameter should not be used for an extended period; after the first piece cache is completed, it needs to be reverted to the default configuration. ---

It should never be set to 3000, even during initial sync ---

Sorry, please forgive me. Many Chinese users get stuck at the Piece cache step for more than 3 days, and some even take a day to complete just 2%. I’ve tried many methods, and the only one that can speed it up right now is this approach. I’m not sure if this setting is useful, but I checked using the performance manager, and the actual number of connections is much lower than this value. I set it to 3000, but the actual number of connections is only a few hundred. ---

I did see piece cache getting stuck for 3 hours myself today, then it mystically moved on on its own. I’m investigating how that could happen and will fix once I know why. If you have a few hundred connections in practice anyway, why not configuring it to that from the beginning then? ---

If I use the default configuration, the actual connections are only in the tens or even lower, and the same goes for the node. I don’t know the reason. ---

That is why I suggest trying 500 instead, but not higher.
