What is overhead? - Stack Overflow Protocol overhead: Ethernet frames, IP packets and TCP segments all have headers, TCP connections require handshake packets Thus, you cannot use the entire bandwidth the hardware is capable of for your actual data You can reduce the overhead by using larger packet sizes and UDP has a smaller header and no handshake
network programming - what is overhead, payload, and header - Stack . . . The overhead of a packet type is the amount of wasted bandwidth that is required to transmit the payload The packet header is extra information put on top of the payload of the packet to ensure it gets to its destination The overhead is variable because you can choose a different type of packet (Or packet protocol) to transmit the data
What is the actually memory overhead in Java? - Stack Overflow With a 16 byte object alignment the JVM can address 64 GB with 32-bit reference (however the padding overhead is higher and might not be worth it) IFAQ: Why is it slower at around 28 - 32 GB While the reference can be multiplied by 8, the heap doesn't start at the start of memory It typically start around 4 GB after
In MySQL what does Overhead mean, what is bad about it, and how to . . . This overhead is bad for table scan, i e when your query needs to run over all table values, it will need to look at more empty space You may get rid of the overhead by running OPTIMIZE TABLE that will compact your table and indexes
What is the overhead of a context-switch? - Stack Overflow The overhead can never be completely eliminated, but changes in architecture like the above quote can help mitigate the overhead There is no one answer to what that overhead is, because it depends highly on the hardware you have, the exact version of the operating system you have, the configured options in the kernel, the compiler and optimization levels used to build the kernel, and quite a
Operating System Overhead - Stack Overflow Try to distribute your process across multiple cores, even multiple (hosted) machines; particularly important when processing time is proportional to the size of an ever-growing data set Any other optimizations (less OS overhead, assembly code) might be surpassed by faster hardware (Moore's law) by the time you completed your effort
What is the memory overhead of a . NET Object - Stack Overflow It's implementation-specific, but for the Microsoft NET CLR v4, the x86 CLR has a per-object overhead of 8 bytes, and the x64 CLR has a per-object overhead of 16 bytes However, there are minimum sizes of 12 and 24 bytes respectively - it's just that you get the first 4 or 8 bytes "free" when you start storing useful information :)

Recursion overhead -- how serious is it? - Stack Overflow My employer wanted highly optimized code for computationally difficult tasks I remember being advised more than once to rewrite recursions as loops, even at the expensive of readability, in order to avoid "recursion overhead " As I understood it then, recursion overhead was the extra effort required to push data onto a stack and later pop it off
