Poor stdio performance on μARM #440
Comments
ARM Internal Ref: IOTMORF-322 |
We're looking into the performance with the updated SD card implementation over here: #4207 Additionally, there's been quite a bit of work around the Filesystem APIs, as well as removal of uARM as a toolchain, so I wonder if these performance issues are still present. |
Closing this, please reopen if issue still exists with latest driver. |

File I/O performance is currently very poor when using FATFileSystem on the μARM toolchain. This is made evident by the attached SD card benchmarks. More details are available here.
