cache is increased from 4MB to 8MB.
(2) "Secondleveldatacache" (Improve CPU Performance): CPU processing speed is much greater than the memory access speed, and memory is much faster than the hard disk. In this way, between the CPU and memory, between memory and disk to affect the performance of the bottleneck, the previous "LargeSystemCache" is designed to alleviate memory and disk bottlenecks, and the CPU in order to be able to quickly obtain processing data from memory also set a buffer mec
Although the minimum installation requirements for the WIN7 system are 1GB RAM, this memory can be very tight when the system is running. So many users will choose to buy a 1GB memory to upgrade the computer to 2GB capacity, but the system reaction speed changes little. Into the system settings to find that, although the system can identify 2GB memory, but only 1GB
/*** Function: Given an input file, contains 4 billion non-negative integers. Produces an integer that is not in the file. Memory Limit: 1GB* Advanced: Memory limit 10MB.*//** * Idea: * * 1) Create bit vectors that contain 40个亿个 bits. the bit vector (bv,bit vector) is actually an array that uses an integer (or another data type) array to store the Boolean values compactly. Each integer can store a string of 32-bit or Boolean values. * 2) Initializ

corresponding n-bit wide, half clock cycle data transmission on the I/O foot.The read and write operation of DDR3 SDRAM is a directional burst operation, starting from a selected position, the burst length is 8 or a chopped burst mode with the length of the programming sequence of 4. The operation starts with the active command, followed by a read/write command. The active command concurrently contains the address bits to select the Bank and row address (BA0-BA2 Select Bank, A0-A15 select Row).
Problem: "The cache is 1GB, even if the write speed peak 400mb,2.5 seconds cache is light, but the hard disk write speed will not be higher than 100MB, even if 3 seconds, also even if only 3 seconds, below the turtle speed, is this mean?"
Answer: In reality, there are few situations where you write at 400MBps for a long time. Imagine how many times a week you write more than 1GB of data to a mobile drive?

First look at the VPS is what: plain English is that it is from a physical server divided into multiple ' virtual ' server, has its own independent public network IP, independent memory, independent CPU, independent operating system configuration, independent hard disk space, etc., can be convenient to restart the server alone, its own installation program, Like a smaller version of the physical server, use it to do multiple virtual hosting, Enterpris
I personally feel that this platform has poor autonomy, whether it is for customers or carriers. For customers, this platform is a virtual operating system and cannot be set on their own in many aspects. It is typical of Windows virtual memory management, which is not good. For sellers, the operation of this platform is inseparable from the support of swsoft. Of course, small-scale operators do not have enough technical strength to maintain the platform, but they must still be unable to do witho
Personally feel the platform is less autonomous, whether it is to the customer or to the operator. For customers this platform is a virtual operating system, many aspects are not autonomous settings, typically Windows virtual memory management, very bad. For businesses, this platform can not operate without swsoft support, of course, the smaller operators do not have enough technical strength to maintain, it is certainly inseparable from this price is not the "support" of the Philippines, but fo
If you think that the virtual host cannot meet your needs, want more resources, and feel that the whole machine is a waste, the VPs server may also be suitable for you.
In terms of price, the VPs host is between the virtual host and the host lease. The performance of the website is more stable than that of the virtual host. users on the VPs do not compete for
