We are experiencing periods of time when CPU utilization of our application goes to %100 percent for several seconds. I tracked this down to two CLR methods which are called when ‘new’ objects are created. The first being ?JIT_New@@YIPAVObject@@PAUCORINFO_CLASS_STRUCT_@@@Z. The second being ?JIT_NewArr1@@YIPAVObject@@PAUCORINFO_CLASS_STRUCT_@@H@Z. The size of the objects being created are relatively small. I understand that there is more to memory allocation then just getting memory, and that Garbage Collection might also be involved. I also understand that it might spike the CPU. But why would the spike last so long, upwards to 5+ seconds? Any insight would be greatly appreciated.
Thanks
