Hello,
I'm building a simple program that has a dependency to
github.com/DataDog/zstd, a wrapper of a C code.
So by default, Go will use the external linker. When debugging with, I can
see
host link: "clang" "-m64" "-Wl,-headerpad,1144" "-Wl,-no_pie"
"-Wl,-pagezero_size,400" "-o"

On x86-TSO model, it seems that we don't need any mfence to archive
acquire-release semantics. Acquire-release semantics only need compiler
barrier to prevent compiler reordering, see https://godbolt.org/z/7JcX-d .

Hello,
I tried to access RabbitMQ using this AMQP
library:https://github.com/streadway/amqp
I am not sure if this library get updated following the recent RMQ

I think it is kind of intuitive that empty struct takes 0 bytes whereas a
bool variable takes 1 byte in memory and hence a map with struct{} values
would consume lesser memory than the other. I tried checking this using
code and Randall's point proves:
mapmem.go:

It looks like the mechanism used by C's std::atomic would not be useful for
us.
We require release semantics on atomic stores. That is, if one thread does:
.. some other writes ...
atomic.StoreInt32(p, 1)
and another thread does
if atomic.LoadInt32(p) == 1 {
.. some other reads ...
}

The top command will show you the memory that the program has requested
from the operating system and has not returned to the operating system.
The Go memory allocator works by requesting memor
Also, it may just be that the runtime is better off allocating more and not
doing a GC based on available memory and CPU usage. The “max heap” feature in
development may help here.

Guessing based on your latest description: are you aware that there is no
partial slice collection in GC? That is:
> bigSlice := make([]int, 1000*1000)
subSlice := bigSlice[0:1:1]
bigSlice = nil
runtime.GC()
// At this point, bigSlice is still allocated! It cannot be freed by the GC

The Linux kernel has TLS; one reason is to allow sendfile(2) with TLS. But
I guess Go doesn't enable that yet?

Basically using the Top command at end of test.
Let me give a quick summary of the scenario.
Basically we have an application which keeps getting data on a TCP
connection, we allocate a global slice to temporarily hold the data and
then store in nested maps.
For every TCP data transaction, we stor
Depends on how the file descriptor is implemented. But the end result probably
has the same performance unless the network card is doing the TLS - which is
possible.

TLS needs encyption, not jost "shoveling the bytes" to the underlying

Ali, your example has several problems.
First, you do this:
var p Person
data, err := json.Marshal(p); if err != nil{
fmt.Println("Error", err)
}
What this does is encode an empty object, that's fine.
Next, you read the HTTP body from the request, and try to unmarshal that.
fmt.Println("Data",
is it mentioned anywhere such that "map[string]struct{}" is efficeient?

Ali, that demo doesn't run given there's no http environment in the
playground. I assume this issue is not HTTP specific.
Something more like this (obviously change your data where it doesn't parse
what you want):
https://play.golang.org/p/RACYspxInyA
Also, please don't store or recreate passwor
req := &mystruct{}
json.NewDecoder(r.Body).Decode(req)
We've instrument the above code block and reading request body bytes is
taking very long i.e., upto 5 secs sometimes reaching upto 20 seconds at
the throughput of ~4-5K RPM
The Request Body Size Metrics are as follows
Average: 73190 Byt

hello Elias,
as far as I understand, GIO is a 2D GUI lib, maybe similar with Flutter,
is it possible to embed one/multi 3D widget inside a view/window?
any architecture thinking on such requirement?
