The counter may indicate 0 bytes/sec if the sampling frequency is higher than the collection frequency since the counter is only updated at the beginning of each collection. This does not mean there were no allocations; rather, the counter was not updated because no collection happened i...
virtual space if virtual memory is overly fragmented. It's not common for the managed heap to cause fragmentation of virtual memory, but it can happen. For example, it might occur if the app creates a lot of temporary large objects, causing the LOH to constantly acquire and release segments...
is similar to the cold startup case except that it affects not just program instructions, but all memory—including memory that was initialized by your application. Since servers run many unrelated programs simultaneously and continuously, servers are application switching constantly; this means that ...
2. The Trump administration seems intent on tossing recent history down the memory hole.Admittedly, Americans have never been known for their strong grasp of facts about their past. Still, as we struggle to keep up with the constantly shifting explanations and pronouncements of the new administrati...
and that’s a danger for the rest of us. Think of the Trumpian past as a website that can be constantly updated to fit the needs of the present. You may believe you still remember something that used to be there, but it’s not there now. As it becomes increasingly harder to find,...
net/http API is stable, while fasthttp API constantly evolves. net/http handles more HTTP corner cases. net/http can stream both request and response bodies net/http can handle bigger bodies as it doesn't read the whole body into memory net/http should contain less bugs, since it is used...
Each DRAM cell stores a positive or negative charge held in an electricalcapacitor. This data must be constantly refreshed with an electronic charge every few milliseconds to compensate for leaks from the capacitor. Atransistorserves as a gate, determining whether a capacitor's value can be read ...
This configuration parameter can be updated dynamically. Care should be taken when updating this parameter, as setting the value too low could cause excessive memory thrashing on the box (memory pages constantly being committed and then released), and setting the value too high might prevent the ...
It is normal to expect the saw-tooth pattern and memory going up in a Java application, even if the application is idle.As it is not efficient to clear the memory on a mostly idle application constantly, the memory will slowly grow until a large amount of the memory is used. This...
A segment's access pattern may be atypical if it is constantly accessed (that is, hot) or infrequently accessed (for example, a large segment accessed by a batch job only once a day).Multiple buffer pools let you address these differences. You can use a KEEP buffer pool to maintain ...
