Media manger seach times out

Hey there, I am using October 2 and have the site hooked up to an S3 bucket for storage. I have hundreds of images in lots of folders and sub folders in media manger and I find when I search in media manager its slow and takes ages ( 45 sec plus at times) sometimes it even times out or gives and gives aa Cloudflare timeout error. Is this a know bug or is there a work around to stop it? cheers
