occupy this block of memory, if the/dev/shm/without any files, it occupies the memory is actually 0 bytes, if it is the largest 1G, there are 100M files, the remaining 900M can still be used for other applications, but it occupies the 100M memory, is never going to be reclaimed by the system. 2. Another major benefit of TMPFS is its lightning speed. Because a typical TMPFS file system resides entirely in RAM, reading and writing can be almost instantaneous. 3. TMPFS data is not preserved afte

half of the available memory. It has been found that the more memory you allocate to the JVM, the greater the likelihood that the above error will occur, given the large number of threads.Each 32-bit process can use up to 2G of available memory, because another 2G is reserved by the operating system. This assumes that 1.5G is used for the JVM, and then the remaining 500M of available memory. This 500M part of the memory must be used to load the system DLL, then the real left is perhaps only 400
