kicad footprint

the 1-minute check once, I changed to be the first time check! , and found no reduction of 0 0. I don't know what the reason is. Should be looking for hash, ask the node, and then go back and ask the inside node, the last number of more and more, but I do not understand how to run so much more than a minute to have 600,000. That is to say, there are so many objects in memory that were not released. When this memory footprint is reached, the basic wil

introduces the format of the Smaps file, By analyzing the Smaps file we can learn more about the usage of process physical memory, such as how much space the Mmap file occupies, how much space is consumed by dynamic memory, how much space the function call stack consumes, and so on. Two concepts about memory To understand the output of the top command with regard to memory usage, we must first figure out the two concepts of virtual memory (fictitious Memory) and resident memory (resident Memory

. This consumption is mainly sortlist insertion, internal sorting and removal of records. When it comes to the choice of sortlist or sortdictionary, and then find some information, sortdictionary in the internal use of red-black tree implementation, sortlist using an ordered array implementation, in the internal sort are O (logn) under the premise , the time complexity of Sortdictionary O (LOGN) inserts and deletes elements is better than sortlist, but sortdictionary consumes more memory than so

index, and if the condition is like '%abc ', MySQL will not use the index.ü In an order by operation, MySQL uses the index only if the sort condition is not a query condition expression. However, in queries involving multiple data tables, even if an index is available, those indexes have little effect in accelerating the order by operation.ü If a data column contains many duplicate values, it will not be very effective even if you set up an index for it. For example, if a data column contains t

MySQL memory consumption is too large, resulting in server memory is very tight, and msyql and other processes in the running process often crashes.
