I am woring on a small project which requires a lot of ram. I've got esp32 s3 in my hands operating 8mb of flash and 2mb of psram, both are using QSPI in this config.
So whenever i try to enable psram the entire script greatly slows down no matter what i do. Even without allocating space it does the same. The only external device i use is SPI tft screen operating 240mhz spi (yeah, it works fine). I understand that external ram works much slower than on-chip one but i think and hope the issue appears only because of my incopetence. Any sugestions and thoughts would be useful
Perhaps you should use google to determine the operating characteristics of all the memory devices you are using so you can evaluate the situation yourself.
