This sort of statement is ridiculous; people making it are either incredibly uninformed, or incredibly dishonest. In particular: The speed of dynamic memory allocation in the two cases will depend on the pattern of dynamic memory use, as well as the implementation. It is trivial for someone familiar with the algorithms used in both cases … Read more
I’ve browsed the EsLint docs hoping to find an option to configure it to run with more memory. Sadly I was not able to find anything of the sort. However, inspired by @vsemozhetbyt’s answer -hence the up-vote- I started looking at Node’s configuration options and I’ve found a way to get around this using Node’s … Read more
You can’t set max heap size in .Net unless you host the CLR yourself in a process. Edit: To control the memory allocations of CLR including the max heap size, you need to use the hosting api to host the clr and specifically use the “Memory manager interfaces”, some starter info can be found here … Read more
Here’s what Oracle’s documentation has to say: By default the heap dump is created in a file called java_pid.hprof in the working directory of the VM, as in the example above. You can specify an alternative file name or directory with the -XX:HeapDumpPath= option. For example -XX:HeapDumpPath=/disk2/dumps will cause the heap dump to be generated … Read more
Terracotta DSO works by manipulating the byte code of your classes (and the JDK’s classes etc). The instructions on how and when to do this are part of the Terracotta configuration file. The bytecode modification looks for certain byte codes such as a field read or write or a monitor enter or exit. Whenever those … Read more
In Sun’s JVM, last I knew, the entire heap must be allocated in a contiguous address space. I imagine that for large heap values, it’s pretty hard to add to your address space after startup while ensuring it stays contiguous. You probably need to get it at startup, or not at all. Thus, it is … Read more
An object is identified by its address. If you want it at another address, you have to construct a new one; you can’t move objects. (Even with C++11, the new “move” semantics don’t actually move an object; they provide an optimized way of moving its value, if you know that you won’t need the value … Read more
When you call a function like this f 42 (g x y) then the runtime behaviour is something like the following: p1 = malloc(2 * sizeof(Word)) p1[0] = &Tag_for_Int p1[1] = 42 p2 = malloc(3 * sizeof(Word)) p2[0] = &Code_for_g_x_y p2[1] = x p2[2] = y f(p1, p2) That is, arguments are usually passed as … Read more
