Slow transfer speeds

Hi there, i am new to truenas and have be using truenas scale for about a month but I have noticed that I am getting slow transfer speeds when using the SMB share when lots of files (total size 10Gb). it runs fine but about halfway through it slows down to a write speed of 6.2MB/s. i am using 4 SSD each 2tb in size and so far have only used 3% of the space. SSD Brand: Silicon Power A55 2TB Is this normal behaviour? does anyone know why this could be happening? [Truenas write performance]
