php smarty 缓存施用
php smarty 缓存使用
一、使用缓存 ? 要开启smarty的缓存,只需将caching设为true,并指定cache_dir即可. ? 二、清除缓存
? 四、局部关闭缓存
写成block插件: 2) 编写程序及模板 现在运行一下,发现是不起作用的,两行内容都被缓存了 你也可以直接将原句的最后一个参数改成false,我对smarty的内部机制不太了解,所以加了一个判断,只要block是 cacheless的才不作缓存 4)OK,现在清除template_c里的编译文件,重新运行,起作用了吧? |

Moondrop has released the Block true wireless earbuds for audio enthusiasts that sit comfortably in the outer ear. Unlike earbuds jammed into ear canals, the Block does not cause a plugged ear feeling or collect ear wax. The 13 mm driver is enclosed

The thing is actually like this. At that time, my leader gave me a perf hardware performance monitoring task. During the process of using perf, I entered the command perf list and I saw the following information: My task is to enable these cache events to be counted normally. But the point is, I have no idea what these misses and loads mean.

Using the cache can increase the speed of the computer because the cache shortens the waiting time of the CPU. Cache is a small but high-speed memory located between the CPU and the main memory DRAM. The function of Cache is to increase the rate of CPU data input and output; Cache has a small capacity but fast speed, while the memory speed is low but has a large capacity. By optimizing the scheduling algorithm, the performance of the system will be greatly improved.

The difference between null and NULL in C language is: null is a macro definition in C language, usually used to represent a null pointer, which can be used to initialize pointer variables, or to determine whether the pointer is null in a conditional statement; NULL is a macro definition in C language A predefined constant in , usually used to represent a null value, used to represent a null pointer, null pointer array or null structure pointer.

In JavaScript, both undefined and null represent the concept of "nothing": 1. undefined represents an uninitialized variable or a non-existent property. When a variable is declared but no value is assigned to it, the value of the variable is undefined , when accessing properties that do not exist in the object, the returned value is also undefined; 2. null represents an empty object reference. In some cases, the object reference can be set to null to release the memory it occupies.

Characteristics of cache: A one- or two-level high-speed, small-capacity memory set between the CPU and the main memory. The information is naturally lost when the computer is powered off. Characteristics of ROM: it can only read data from the memory, but cannot write information into it. The data will still exist after the computer is powered off. Characteristics of ram: it can read data from the memory and write information to the memory; it is used to store commands, programs and data required to run the program; information is naturally lost when the computer is powered off.

Cache is called cache memory. It is a high-speed small-capacity memory between the central processing unit and the main memory. It is generally composed of high-speed SRAM. This kind of local memory is oriented to the CPU. It is introduced to reduce or eliminate the gap between the CPU and the memory. The impact of the speed difference between them on system performance. Cache capacity is small but fast, memory speed is low but capacity is large. By optimizing the scheduling algorithm, the performance of the system will be greatly improved.

Here is the tutorial for nginx reverse proxy caching: Install nginx: sudoaptupdatesudoaptinstallnginx Configure reverse proxy: Open nginx configuration file: sudonano/etc/nginx/nginx.conf Add the following configuration in the http block to enable caching: http{...proxy_cache_path /var/cache/nginxlevels=1:2keys_zone=my_cache:10mmax_size=10ginactive=60muse_temp_path=off;proxy_cache
