Can anything be done to speed up Roundcube on a Celeron 700 with 512MB RAM (maxed out) running Gentoo Linux? We're using the Chrome browser and the CPU is 95% idle when no one is logged into X. I'm getting reports of 30+ seconds to open an email.
no - you should be happy that it runs at all on hardware outperfored by years old smartphones
What are the Roundcube recommended minimum specs?
