The PSP browser is slower compared to modern browsers and often runs out of memory due to limitations put in place by Sony. Alternatively, homebrew alternatives to the browser have been released that utilize all 32/64 MB of the PSP's RAM, which allows the browser to load pages faster and have more memory for larger pages. Opera Mini can also be used on PSP through PSPKVM, a homebrew application which is a Sun Java Virtual Machine. It was claimed to provide much faster loading times than the default browser and provides better web page compatibility.
