zynq 7010 microzed sluggish CPU response

I have ubuntu based OS installed on my zynq 7010 based microzed board (commercial version) and having certain scripts running on them outdoors. I have 10 such systems outdoors. But on two particular systems, whenever I login to these system, the response from the terminal is very sluggish and CPU itself seems to have slowed down. After I reboot the system, then it would start running normally, and then again after a few hours, shows up the same behavior. What could be the possible reasons for this ?

 

Some process is utilizing maximum CPU resources ?

Or the 8GB SD card quality isnt good ? What SD card is recommended to be used if so ?

Slow performance after a few hours sounds like a memory leak to me - something's allocating a bunch of memory and not giivng it back, so the CPU is having to use the disk (SD card) for temporary storage. Try using the "top" command - that should show you both what's using CPU time and what's occupying all the RAM.
