Did you use some other conversion options as I used above and if so, could you post them?

I don't think that Sony readers generally have a problem with large xhtml files within an ePub but I think that this is specific to the conversion used with this plain text file. I don't know if this is related to the fact that every line has become a paragraph or that there are no chapter breaks, (and therefore the reader is somehow having to process the whole book as one huge chunk.) The slow down can also be seen in ADE on a PC, though it's less obvious because the PC is a lot more powerful that the reader.
Conversion options were
TXT Input > Paragraph style > single
TXT Input > Formatting style > none
Look & Feel > Extra CSS > body { font-family:monospace }
Page Setup > Margins > Left:5pt, Top:12pt, Right:5pt, Bottom:12pt
ePub Output > Split files larger than > 64KB
The book was then given a minor tweak using calibre's Tweak Book option:
1) .calibre style was given font-size:0.8em (a better starting point on my reader which only has 3 zoom sizes).
2) .calibre1 style was removed and . . .
3) P style was added (have a play with top-margin and line-height in em).
4) All class="calibre1" styles were removed from the .html split files since they were made redundant by steps 2 and 3. (Did this just to reduce the filesizes).
(If you get more styles like .calibre2, .calibre3 etc. then these can also be removed and the styling incorporated in the P styling).
And finally
If you are prepared to spend a bit of time using Markdown with your plain text file then a better conversion could be achieved, complete with 'chapters' and a table of contents - but you may feel that it is not worth the effort. I reckon this would not show the slowdown effect. I have done many conversions of much larger plain text sources, using Markdown and a file split of 127K, and my PRS-300 shows no slowdown.
Hope this is helpful.
