The first section outlines the features of the snapshot implementation and the application environment, and the second section describes how to create and view snapshots. Part One virtual machine configuration file A virtual machine with the name "Windows Server 2003 SP2" is used in the test environment. When the Windows Server 2003 SP2 virtual machine is created, in this case, the virtual hard disk is stored in the T:\Hyper-V\Virtual Hard disks folder (as shown in Figure 1), and the virtual m

dramatically. Camera The MSI GT60 has a 1.3 million megapixel front-facing camera that is well-behaved and captures real color in natural light with only a few noise. In dim environments, image quality is slightly degraded using the default Windows 8 camera app, we can capture images of 1280*720 resolution. MSI GT60 shooting Proofs Processor and graphics performance The MSI GT60 is equipped with a 2.7 GHz frequency up to the Intel Haswell I7-4800MQ processor, as well as a hybrid stora

The redo log is used to ensure that the write operation is fast and reliable and recovers when it crashes. Until MySQL 5.1, it's hard to adjust, because on the one hand you want to make it bigger to improve performance, on the other hand you want it to be smaller to make it faster to recover after a crash.

the following 3 configuration items frequently. Otherwise, it may soon be a problem. Innodb_buffer_pool_size:This is the first option you should set after you install InnoDB. The buffer pool is where the data and index caches are: the higher the value, the better, which guarantees that you will use memory instead of the hard disk for most of the read operations. Typical values are 5-6GB (8GB memory), 20-25GB (32GB memory), 100-120GB (128GB memory).in
