Go will release memory and return them to the OS, but not immediately.
You can call debug.FreeOSMemory() to tell GC to return memory, but it may not help much. I found debug.SetGCPercent(10) is more helpful. I think you should make your code more memory efficient, you may also want to limit goroutine concurrency to make sure they will not eat up all your available memory. |
As @serika00 says, the two tools available are Note that as this is a question, not a bug report, it shouldn't be on the issue tracker. Please see http://golang.org/wiki/Questions. |
debug.SetGCPercent(10) is usefull, thanks |

What did you do?
i build a shadowsocks local proxy, at windows platform, it just use 5,6, top 8m memory, but when i use
gomobile bind -target=ios proxyproject/my/net
invoke the function in IOS network extension,
the memory of PacketTunnel start at 6m, and glow to 15 after use safari, 15m is the limit of network extension, when memory use 15m, ios will kill the PacketTunnel
why gomobile export function not release memory to system?
I do call runtime.GC(), but in windows platform it's ok, but IOS, memory keep growing.
What did you expect to see?
Is there any way to reduce memory on IOS, or return memory to system
What did you see instead?
