Good question, and I don't know the answer. Theoretically if you format NTFS and retest and performance is bad you can use the SD Formatter from the SD Association ( https://www.sdcard.org/downloads/formatter_3/ ) to format it back to Fat32 for optimal performance, but I have never done it and don't know that it would get it back to the same performance it has now. It might be worth using it to format the poor performing one back to Fat32 and retest to see if it makes a difference. That might give you a hint what you want to do with the new one. Thanks, but I decided just to stick with FAT32.

What we are looking for is a reason for SM to load slowly in respect to being installed on a tablet, or PC. Look carefully at the copied version of your profile, use a common text editor, to view only, your Prefs.js file. The Preferences file will point specific loading preferences toward local files. If these files are not present at loading SM, SM will by default try and create them for launch, failure to create default files and preferences may lead to frozen SM. What I am trying to get you to do is make a very careful analysis of the profile you are copying, and make sure all the references in that profile exist on your SD card, and that they are correctly referenced in the profile. I can tell you that I have used a USB Memory Drive to launch SM on a laptop, but there I installed SM on the USB drive, created a shortcut on the desktop of the laptop, plugged in the USB drive, and launched SM.

This happens both with my existing profile (copied from another machine) and a new test profile. The original default profile on the SSD C drive works fine. Has anybody else seen this? Can SeaMonkey be transferring so much data to/from the profile that disk speed is a major issue? BTW, the card is PNY 32GB Secure Digital High-Capacity (SDHC) Flash Card Model P-SDHC32G10-EFS2 R. -- David Wilkinson ___ support-seamonkey mailing list support-seamonkey@lists.mozilla.org https://lists.mozilla.org/listinfo/support-seamonkey
Re: Poor performance with profile on SD card
David Wilkinson wrote: I have an Acer Iconia W500 tablet on which I have installed Windows 8 Release Preview 32-bit (and previously the Developer Preview and Consumer Preview). This machine has a 32GB SSD drive, and I have added a 32GB SD card in the internal slot, formatted as NTFS (drive D). When I put my SeaMonkey profile on this SD card, the performance is abysmal. *Everything* takes a long time, especially just loading pages in the browser.

David, Long, long ago, before smart phones and tablets, or notebooks we were able to install SM on the memory stick that would be used with the mobile device (Acer Iconia W500 tablet). Installing on the memory stick allowed SM to create a default profile on the stick. Some of the files on your desktop install of SM refer to locations on your desktop, not found anywhere on your tablet. Try installing SM on the memory stick for the tablet.
