Hello, We have recently used NAS storage for the Mendix file system in our UAT environment and observed that attachments upload is taking more time now as compared to when the local server folder was used. There is significant deviation and it takes more than 30 seconds even to upload 5 MB file while it takes only 10 secs when local server path is used. Average time to upload attachment with NAS is double for small files and significantly increases when file size increases. Please see matrix below. File Size File Type UAT (NAS) UAT(local drive) 97.79mb xlx 5 min 1m 6 sec 52mb xlx 3min 35 sec 10mb xlx 35 sec 11 sec 5.2mb xlx 30 secs 10 sec 3.6mb xlx 14 secs 6 sec 2.3mb xlx 10 secs 6 sec 1.3mb xlx 8 sec 5 sec We have followed all the steps to change the file system path and NAS is listed as a supported file system. Would like to know if something else needs to be done with NAS storage to get similar upload time as with local server drive storage. Any insight is appreciated. FYI, we did run ping and trace route to the NAS path from UAT server and it was within millisecs. We also tried to manually copying the 10 MB files to the NAS folder from UAT server and it was within fraction of seconds. Thanks, Satya
