[solved] ac86u ml revision firmware virtual memory creation failed, prompting that the USB disk reading and writing speed does not meet the requirements

Subject matter ： Use koolshare Software center virtual memory plug-in creation swap Memory , Tips USB The disk reading speed is no less than 10M/s, The writing speed is no less than 30M/s（PS： Don't you pull the calf , Where can I find it? U Disk writing is faster than reading , And I used to find one U It's over , Now we have to build a highway U disc , It's not a small expense , High end routers are really getting more and more frustrated ）
The main error reporting prompts are as follows ：

USB disk [/dev/sdb] Reading and writing speed is too low , Does not meet the plug-in requirements !
【 Virtual memory 】 Plug in requirements USB Disk device read no less than 20MB/s, The writing speed is not less than 30MB/s, This test speed is the same as USB The actual speed of the disk may vary , The above reading and writing speed is for reference only !
 Under the same test conditions ,RT-AC86U,RT-AX88U Wait for the model flash Read as 10MB/s, Written as 30MB/s

The appended drawings ： Tips for installing the original plug-in

   Enclosed xshell New connection settings for
   

2. Execute the order
   sed -i '7,8c R_LIMIT=20\nW_LIMIT=20' /koolshare/scripts/swap_make.sh
   Explain it. , Is to create swap The partition U Adjust the disc speed limit to the available value , The value can be set to the value you want to set （ Ensure the level of peripherals , If I can't, I'll lower the key ）
   
   Execution completed , Enter the software center again , You can create virtual memory normally . End of tutorial , Life is endless , Toss about , If you have any questions, you can leave a message in the comment area or send a private message to the blogger .
