Ivan, I tracked down the problem to a difference between the generic and optimized versions of the P256 implementations. I'm not 100% sure of the correct fix, so I submitted it as golang.org/issues/20215 with a link to your example. - Todd On Tuesday, May 2, 2017 at 12:33:56 PM UTC-5, Ivan

[go-nuts] encoding/json: unexpected behaviour when unmarshalling into struct with interface{} field

Hey Gophers, When unmarshalling JSON into a struct with a blank interface (interface{}) I get a surprising result: If I set the field to a pointer to a T value before unmarshalling, the data is filled out on the T value as expected. (See I2 in the playground example.) If I set the field to a

My app uses large amounts of memory; it actively allocates and frees lots of slices. I'm talking about gigabytes here. With the default GOGC=100 setting, it needs twice more memory. When I decrease GOGC to a lower value, it affects performance pretty badly. So far the best solution I have

Re: [go-nuts] GC problem

I don't think it is a GC bug, but rather a trade-off of several desirable properties. The system does the following: - allocates 2gb - Since the current heap size is 0 the 10% gc limit is reached and a GC is started concurrently with the program - While the program processes the array, the GC

Re: [go-nuts] GC problem

There is nowhere told that GOGC defines border that could not be reached. GOGC defines proportion that triggers GC, ie GC is triggered AFTER GOGC proportion crossed, not before. In fact, if you allocates by small portions, then GC tries to predict when you will reach this border, and tries to

The allocation request (make) is made to the runtime which covers GC, right? GC percent is also set to 10%. After 1st call returns, my app has about 2gb ram allocated. When 2nd call requests allocation, runtime cannot: - first allocate another 2gb - free the 1st buffer later due to the definition
