lamda server slow #527

Hi Mike,

My commands on the lambda server are running really slowly. What should I do?

hello,

mine is also excruciatingly (however you spell it) slow

Running the atop command right now, I can see that the disk usage of the /data folder is maxed out at 100%, and the CPU usage is hovering between 1500-2000%. (Recall that 100% is the max for disk usage, and 8000% is the max for cpu because there's 80 cpus.)

CPU-bound tasks (everything except mapreduce) should be running normally right now. Any disk usage of the /data folder will run very slowly, but this should only be the mapreduce homework. Your home folders are all stored on a separate hard drive than the /data folder, so you shouldn't run into problems as long as you don't touch that folder. (Technically, the /home folder is on an NVME drive, which is very fast, but very expensive.)
