而如果 -XX:UseCompressedOops 被开启,并且我们没有手动设置过 -XX:-UseCompressedClassPointers 的话,JVM 会默认帮我们开启 UseCompressedClassPointers(详情可查看 hotspot/src/share/vm/runtime/arguments.cpp 中的 Arguments::set_use_compressed_klass_ptrs() 方法)。 我们先忽略 UseCompressedOops 不提,在 Use...
I think this might be solvable via the use of a WeakReference in CompressedInputStream, but I don't know if this use of a WeakReference may cause regression elsewhere. I've attempted to document the investigation into the issue here:
Memory in .NET Applications As you probably know, .NET applications make use of several types of memory: the stack, the unmanaged heap, and the managed heap. Here's a little refresher. The Stack The stack is where local variables, method parameters, return values, and other temporary values...

The name used to describe a RAMIMAGE section must be the same name used in the .bib file that specifies the modules and files to add to the run-time image. Romimage generates one .bin file for each RAMIMAGE entry. After you run Romimage, all noncompressed executable code is fixed up...
Although there are many highly optimized compression approaches in main memory, there is still a considerable performance gap between query processing over compressed lists and uncompressed lists, which motivates this work. In this work, we set out to bridge this performance gap for the first time ...
A memory LSI with compressed data inputting and outputting function provides reduction of data transfer amount and whereby to expand effective passband width with restricting transfer loss upon transfer of variable length compressed data. Data size detection circuit detects a size of a compressed data ...
Variables in an imperative language may use either a value or a reference model, or some combination of the two. In C, Pascal, or Ada, which employ a value model, the assignment A := B puts the value of B into A. If we want B to refer to an object, and we want A := B to...
Both store compressed or decompressed data in an internal memory pool for Serialize/Deserialize. Therefore, it is necessary to release the memory pooling, don't forget to use using.Compression level is very important. The default is set to quality-1 (CompressionLevel.Fastest), which is different...
