There are many ways to build the station profit, optimization means also have a lot of clever methods, I used the method is the most common optimization techniques: content construction, tracing text construction, outside the chain construction. We Anhui Forum Construction Station three months to achieve a monthly income of 5K, I think the most important thing is "stability", that is, we try to do some of the most basic Web site optimization, do not s

Kernel ROM and ram are less expensive than ucos, especially RAM. This is a single-chip microcomputer is scarce resources, ucos at least 5K, and Freeos with 2~3k can also run very well.2. FreeRTOS can use the co-routine to reduce RAM consumption (common stack). Ucos can only use Tasks

of a performance problem, and execution is very fast, but the DBA is very serious about telling us that it has to reduce its frequency of execution. We monitored this SQL and found that there were 20K calls per minute at peak times, and the frequency of calls was very high. After examining the code, many of these simple queries are found in loops. To batch queries, increase the cache where you can increase the cache , and the SQL execution frequency is reduced to 2k-
