I installed Ubuntu 24.04 on Vbox and allocated 6 GB of RAM and 2 processors. It doesn't provide the exact same experience as normal installation, but it seems to have slight lag, is this normal? Processor is 12th gen Intel(R) Core(tm) i5-1235u, 1300 MHz, 10 cores, 12 logical processors. RAM is 32.0 GB (available: 31.8 GB). 64-bit system.
