Some versions of Microsoft Internet ExplorerThe page is only displayed after 256 bytes have been accepted, so you must send some extra spaces to let these browsers display the contents of the page. So, the correct use of the two is the order. First Ob_flush, then flush, Of course, in other sapi, do not cal

Time will consume the CPU cycle. Therefore, if the CPU of the entire system is very full, avoid using this feature. When the network bandwidth is limited and the CPU resources are sufficient, the use of multi-threaded compression dynamic migration technology will bring better results. When the network is sufficient and the CPU resources are sufficient, using this technology will also reduce the total migration time. 3. multi-thread compression and migration technology enabling Method Source end

until it receives the tag. Some versions of Microsoft Internet ExplorerThe page is displayed only after 256 bytes are received. Therefore, some extra spaces must be sent for these browsers to display the page content. Therefore, the correct order of the two users is: first ob_flush, then flush, Of course, other sapis do not call flush, but we recommend that you use it to ensure the portability of your code. If you want to support nginx + fpm + php, you need to add a response header. Header ('x

We can be in the drive there to make a amplification circuit, speed can go up, but can not back, we can directly use the l298n drive.
