Thanks! I had run into the limit before, but I had seen it was getting addressed, I just wasn't sure how. I am not running into any looking now, just wanted to understand what they changed into as we are planning for the future with hardware choices. It sounds like the memory limit is removed comp

If this is important and wasn't fixed in 1.11 or at tip then please file a bug report with a reproducer at https://github.com/golang/go/issues. An issue number will result in the Go team investigating. On Friday, November 16, 2018 at 1:12:58 PM UTC-5, Robert Engels wrote: > > This article > ht

This article https://syslog.ravelin.com/further-dangers-of-large-heaps-in-go-7a267b57d487 would imply it is far less than that. I responded that something didn’t feel right, but maybe Gos lack of generational GC is a real stumbling block here. > On Nov 16, 2018, at 11:58 AM, Matthew Zimmerma

What are the current memory limits? I know it used to be 512gb. Is there a difference between the platforms? I couldn't find documentation on this. Thanks! -- You received this message because you are subscribed to the Google Groups "golang-nuts" group. To unsubscribe from this group and sto

I love this. I write some data analysis code and for ease of development and speed I keep the tables I build in memory. Generating those tables takes lots of memory and CPU, so I disabled the GC and manually run GC when the runtime memory stats start to get close to the system limit. Seems to be w

[go-nuts] Memory Limits in Go

2017-01-24 Thread Yves Junqueira
Hi. I've seen various discussions about adding memory limits to Go, but existing proposals are either impractical or they don't take into consideration important factors such as: - why it's so hard to have predictable memory usage - what's the effect of GOGC to your memory usage - how to
