图片存储用memcached仍是redis
图片存储用memcached还是redis
最近在做一个图片类应用，对图片的读取速度要求很高，一般从物理硬盘的读取速度达不到期望，所以想试试用内存存贮，但犹豫选用memcached还是redis，请大家帮我分析分析我的想法是否可行，还有应该选用mem还是redis。我的需求是：1、写操作不多，主要是读取操作；2、不必考虑内存大小的问题；3、永久存储，容错率要低。谢谢
------解决方案--------------------
redis
1、memcached 的最大容量是受限的
2、memcached 不会自动将内容存于硬盘，不符合永久存储的要求

Analyze PHP function bottlenecks and improve execution efficiency
Apr 23, 2024 pm 03:42 PM
PHP function bottlenecks lead to low performance, which can be solved through the following steps: locate the bottleneck function and use performance analysis tools. Caching results to reduce recalculations. Process tasks in parallel to improve execution efficiency. Optimize string concatenation, use built-in functions instead. Use built-in functions instead of custom functions.
Golang API caching strategy and optimization
May 07, 2024 pm 02:12 PM
The caching strategy in GolangAPI can improve performance and reduce server load. Commonly used strategies are: LRU, LFU, FIFO and TTL. Optimization techniques include selecting appropriate cache storage, hierarchical caching, invalidation management, and monitoring and tuning. In the practical case, the LRU cache is used to optimize the API for obtaining user information from the database. The data can be quickly retrieved from the cache. Otherwise, the cache can be updated after obtaining it from the database.
Which one has better performance, erlang or golang?
Apr 21, 2024 am 03:24 AM
There are performance differences between Erlang and Go. Erlang excels at concurrency, while Go has higher throughput and faster network performance. Erlang is suitable for systems that require high concurrency, while Go is suitable for systems that require high throughput and low latency.
Caching mechanism and application practice in PHP development
May 09, 2024 pm 01:30 PM
In PHP development, the caching mechanism improves performance by temporarily storing frequently accessed data in memory or disk, thereby reducing the number of database accesses. Cache types mainly include memory, file and database cache. Caching can be implemented in PHP using built-in functions or third-party libraries, such as cache_get() and Memcache. Common practical applications include caching database query results to optimize query performance and caching page output to speed up rendering. The caching mechanism effectively improves website response speed, enhances user experience and reduces server load.
How to use Redis cache in PHP array pagination?
May 01, 2024 am 10:48 AM
Using Redis cache can greatly optimize the performance of PHP array paging. This can be achieved through the following steps: Install the Redis client. Connect to the Redis server. Create cache data and store each page of data into a Redis hash with the key "page:{page_number}". Get data from cache and avoid expensive operations on large arrays.

First you need to set the system language to Simplified Chinese display and restart. Of course, if you have changed the display language to Simplified Chinese before, you can just skip this step. Next, start operating the registry, regedit.exe, directly navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlNlsLanguage in the left navigation bar or the upper address bar, and then modify the InstallLanguage key value and Default key value to 0804 (if you want to change it to English en-us, you need First set the system display language to en-us, restart the system and then change everything to 0409) You must restart the system at this point.
