Hi All! I have a very simple program as follows that just creates an
isolate, then sleeps:
#include <libplatform/libplatform.h>
#include <v8-platform.h>
#include <v8.h>
#include <stdio.h>
#include <unistd.h>
using v8::Isolate;
int main() {
std::unique_ptr<v8::Platform> platform =
v8::platform::NewDefaultPlatform();
v8::V8::InitializePlatform(platform.get());
v8::V8::Initialize();
v8::Isolate::CreateParams create_params;
create_params.array_buffer_allocator =
v8::ArrayBuffer::Allocator::NewDefaultAllocator();
Isolate* isolate = v8::Isolate::New(create_params);
printf("Sleeping...\n");
usleep(1000 * 1000 * 100);
printf("Done\n");
return 0;
}
When i run this program, i can then check the number of threads the process
has created with ps -T -p <process_id>, and i see that on my 8 core
machine, v8 creates 7 extra threads all named "V8 WorkerThread", and on my
16 core machine i get 8 instances of this "V8 WorkerThread" created.
I am looking to understand what determines the number of extra threads v8
spawns and what the purpose of these threads are. Thanks in advance!
Joel
