I finally found the time today to install OZ 18.104.22.168 (GPE) on my C750. I am very impressed with the result. It is evident that a lot of work has been put in this version.
I have however a problem that renders my installation almost unusable.
My SD card, a Toshiba 512 MB, is extremely slow: read speed is around 300 KB/sec and write speed is around 20 KB/sec. The card was working perfectly on older versions of OZ (and pdaxrom).
The card has one partition with the ext2 fs. I tried recreating the partition and the filesystem but I didn't see any improvement.
The card seems to be working (tested in a cardreader and also I don't see any relevant messages in dmesg output). Is there a way to improve its speed in OZ?
