/how-to-drastically-improve-your-app-with-an-afternoon-and-instruments) There are some code that can be used to parse the ISO-8601 date string, and simply rewrite it to use it.Well, just use C to make it look good, but do you believe that we have a better plan!If you can control the date format you are working with, try to choose a Unix timestamp. You can easily convert from timestamp to NSDate: -(nsdate*return[NSDate datewithtimeintervalsince1970:timestamp];}This will be faster than using C

operations.1. Modify the sequential logging to in-page logging to avoid repeated erasure of the same position.2. A large number of In-place update random writes are combined into a few sequential writes in a cache-write manner.3. The use of high-capacity SSD random read and write capabilities, reduce write increase read, so as to achieve overall performance improvement.4. Control Panel-management tools-Ser

configuration. Linux is rich, powerful, and flexible, and you can do a variety of tasks with it, and in this article we'll discuss some tips for improving the performance of Linux servers.1. Tuning the Linux kernel elevator algorithm for disk I/OAfter selecting the file system, there are some kernel and mount options that may affect its performance, one of which

This article mainly tells you that there are 20 difficult problems in DB2 Performance Tuning. In actual DB2 database design, the physical design should be as close as possible to the logical structure, however, physical design changes made for DB2 performance cannot be ignored because they do not come from logical design. 1. Logical design should always be fully

also true for static,final, constants).Often estimatedBefore you start optimization, make sure you have a problem to solve: Make sure you can measure your existing performance accurately, or you will not be able to observe the improvements brought about by optimization.The datum point is created by the caliper's Micro datum frame. The datum points are hard to get right, so caliper does the hard work, even when you're not measuring where you want to m
