monitoring results indicate that disk I/O is not used in large quantities. why is MySQL? Use disk I/O to start flushing before a problem occurs to relieve the pressure on the problem. The reason is that MySQL has an adaptive disk flushing method to control the entire refresh process. innodb_adaptive_flushing, innodb_io_capacity, innodb_max_dirty_pages_pct, and redo log size to determine when Start to refresh the dirty page. how can this problem be solved? in general, MySQL will judge whether th

In various technical means to achieve broadband access, the optical fiber access network is the most suitable for future development solutions, especially the ATM Passive Optical Network (ATM-PON) it is almost an economical and effective way to integrate broadband access.

Halfwidth to fullwidth: the first byte A3 is added, and the highest position of the original byte is 1.Full-width to half-width: discard the first byte, and the second byte is at the highest position of 0 Space The space of the ASCII code is \ x20, and the space of GBK encoding is A1A1 Unlike English letters and symbols, this should be special Control characters 0-31 characters in the ASCII table,

long time, the use of the already well-known angular + Bootstrap, or the use of more new technology Angular2? 1 or 2? With 1 words because I have been a Web product for two years, can be said to be extremely easy, the language should not be a problem, the next step in the structure and the business to make clear that the rest should be the physical life. But also unwilling to heart such a good opportunity, do not engage in the latest Angular2 how worthy of their own? So after the discussion wit
