Re: [orca-list] Sluggishness in Orca

[Andy Borka <sonfire11 gmail com>]

Try using Orca master. There are probably tons of fixes since 3.28 since 
we are now up to 3.32.2 pre. According to Ubuntu documentation, Ubuntu 
18.04 requires a minimum of 2GB of memory, a 2.0GHZ dual-core processor, 
a DVD drive or USB slots that can boot uefi enabled media, and a video 
card that can support at least 1024x768 resolution. This isn't the 
minimum hardware to get best performance though. Instead, it is the 
minimum amount of hardware that will get Ubuntu booted and running. As 
the documentation mentions, the better the hardware, the better the 
performance. As you mentioned, Ubuntu and Orca are seriously crippled 
with the computer having 1GB of memory. This makes sense because the 
minimum is at least 2GB of memory (DDR3 or better recommended). In most 
cases, a 2.0GHZ dual-core processor isn't present on the computer with 
1GB memory. This also may contribute to the lack of performance. The 
laptop with 6GB of memory probably has a 1.5GHZ or 1.7GHZ I3 or I5 
dual-core processor. If so, this computer still doesn't meet recommended 
minimum requirements. Test these 4 problems on a higher end computer to 
ensure they are resolved before settling down with Ubuntu 18.04 and 
later on a lower end computer. For reference, the documentation is found 
at https://help.ubuntu.com/community/Installation/SystemRequirements. My 
laptop has the following hardware: 16GB DDR3 memory, I7 8550u 1.80GHZ 
(2.5GHZ) x 8 processor, 1TB HD, and display that supports 1920x1028 
resolution.
