Bill Asks: I have a user who is experiencing system slowness while working on a 16 MB drawing and saving a 660+ MB solution file (.sol). What could be the reason? What can the user do to improve performance?
Dave’s Answer: The user is an idiot. Fire them and hire a new person from any nearby bus stop to replace them. No, seriously though, just check the usual suspects:
- Check Disk integrity (free space, errors, fragmentation, etc.)
- RAM (needs 4GB as bare minimum) – and check concurrent / background processes
- CPU shouldn’t be an issue.
- NIC shouldn’t be an issue – it loads the data into RAM regardless of source location
- File Size – not an issue unless RAM and Disk are not up to snuff.
- If the Disk is to blame, replace spindle drive with an SSD. If budget allows, buy two (2) and use one for the OS and the other for data storage.
- If RAM is to blame, add more.
- If the CPU is to blame, buy a new computer.
- If the NIC is to blame, buy a new computer.
- If drawing File size is too large, and they’re not working for Pixar or Disney, make sure the user isn’t building a porn animation project (unless that contract pays really well)
Basically, AutoCAD manages (mostly) vector and (some) raster data. It leans heavily on CPU, RAM and Disk I/O, unless 3D or rendering tasks are involved which tap into the GPU. Aside from that, the rest is up to RAM and paging, and of course: budget.
