First of all, let me explain my point: I work as the sole code developer at a small tech company. Since some months ago we have been working with lots and lots of data analysis, which is getting heavier everyday. The computer I work with isn't exactly bad, but it's not optimized for data analysis and performance (with even my home computer processing stuff better). But since I am the only IT professional in the company, it isn't that easy for my employers to realize why sometimes it takes me lots of hours to execute some processes due to computers not working optimally.
Since this is my first job, I'm not very sure if it would be inappropriate to recommend the purchase of a new and more powerful machine. My productivity would certainly increase without having to reinitialize the computer multiple times, but I'm unsure if I should say it directly.
