Thumb drive: performance, web browsers, disk reads and writes
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}
Lubuntu 19.04. Installed from thumb drive (USB 3.0 32 gb Yumi UEFI) to USB 3.0 64 gb. Partitions are 200 mb fat32 (/boot/efi), 50 gb ext2 (/) and 8 gb fat32 mounts on /media , no swap. Test system is Core I5 gen 7, 16 gb memory. System boots and plays. Performance is intermittently sluggish and appears to be related to DISK I/O. When performance is bad the LED in/on the thumb drive is flashing constantly. Installed "iotop" and confirmed web browsers (firefox, chrome) do a lot more writing to the disk than I expect. Disabled "lxqt Power Management" because it appeared to be contributing to disk i/o.
My goal is to use the thumb drive as a portable dokuwiki/demonstration. I have installed apache, it works and am stumbling through the dokuwiki self-education process. Demonstrating dokuwiki with a web browser, booted from the thumb drive, appears problematic given that disk activity gets in the way of performance.
I am not using a casper-rw file system. Does anyone know that casper-rw does not exhibit similar disk i/o behavior.
Has anyone else seen this behavior on thumb drives? Should I use ext3 or ext4 for "/" and/or allocate a swap partition. Memory utilization never approaches the 16 gb of the test system, so I am assuming swap is not necessary.
