[go-nuts] Perf : Multithreaded goroutines files I/O

Hello, I have a loading step, where I have something like 60 files to read and process, as fast as possible. I tried loading with goroutines and without, and I get substantially the same process time (38s). *What is the more idiomatic ? Is Golang designed for concurrent files I/O ?* Note : One

Re: [go-nuts] JSON decode streaming : Go forward when format is not json

Thank you both for your answers. It's true that there is a convention for JSON streaming in which one each json message is followed by a '\n'. There is + and - for this convention. *+ :* -> I can detect bad JSON *- :* -> The most important : It's a little more painful for final user. It's al

[go-nuts] Re: Can somebody explain the importance of 'select'?

Let's say you make a sudoku solver, as fast as possible. You have a multicore computer. If the disk read or parsing is slow, you are going to prepare sudoku files in 3 goroutines, let's say. And the 4th thread (the main thread, let's say) will solve them. How the main thread can get sudoku to so

[go-nuts] JSON decode streaming : Go forward when format is not json

Hello, I build a service receiving Json from websocket. I use json decode. I want my service to be robust ! *var tmp interface{}* *err = this.reader.Decode(&tmp)* My problem is : When I got some error here, I came to infinite loop, because the decoder doesn't go forward. It seems that it is t

[go-nuts] Re: package net/http/pprof causes memory increase

It seems that the function follows accumulates: Runtime / pprof.writeHeap + 0x29b6 This is what is observed in /heap. The number of it increases but never decreases. Le mercredi 4 janvier 2017 07:52:25 UTC+1, Dave Cheney a écrit : > > Can you provide a runnable sample which shows the problem? > >

[go-nuts] Re: package net/http/pprof causes memory increase

Hello, Thank you, I was going to launch the same subject. I see the same thing. When I access to /debug/pprof, there is the "heap". And I got the detail in "debug/pprof/heap?debug=1" I get more heap when I refresh the /heap page. And it never decrease. Thank you for your help Le mercredi 4 j
