Three key factors directly influence the speed of the proxies:
The internet upload speed is provided by the router.
The strength of the signal received by the modems.
Data plan caps (if found/applied).
Consequently, a faster upload speed from the router will result in improved proxy speeds.
Moreover, the physical location of the hardware setup is equally important, as a favorable location with optimal signal reception can positively impact the overall speed and performance of the proxies. Hence, carefully considering these factors is essential to achieve optimal proxy performance during the hardware setup process.
