Msg: Re: speed of vdosplus

Wengier,

These are documents with multiple style changes per page (with the "use" command), using different margins and indentations, but no bold/italic text. I tried removing all that style formatting, so it's just default margins throughout, but that made no difference.

Hi John,

Are you viewing a pure text documents or documents that contain a lot of styled-text like bold/italic text? I am trying large mostly pure text documents in Xy3 and Xy4 on my PC but have not noticed the differences in speed yet...

Wengier,

I don't use Wheelmod, but explicitly disabling it with 0,0 has no effect. At least one place where the difference is obvious is flipping backwards from the end of a large document to the beginning, in one page increments (alt+pageup). The older version is very smooth and very fast (far too fast to actually read anything). On the more recent versions, it's jerky/uneven in movement and maybe a third of the speed.

It's not consequential in any way, but just something I noticed....

Hi John,

The executable you sent me is build 2016.08.05. The differences between this build and the later 2016.08.14 build you mentioned earlier are support for small text, block comments and mouse wheels. I don't think the block comment feature will impact the XyWrite running speed in any way because the config file is only read at the start. To see if the mouse wheel support feature may cause the speed change, you can try disabling this feature by setting WHEELMOD=0 or WHEELMOD=0,0 in the newer build and see how it works. I have not noticed the speed difference in my own computer yet, so I cannot say it myself. Hope this helps.

Wengier,

I found an earlier version of vdos-lfn, 1216KB, with a date stamp of early August (which may not not reflect the actual creation date). I tried to attach it, but the system apparently won't accept files; I'll send it to your personal yahoo address, listed on the vdosplus page.

Using the same config.txt file, it's notably faster than current vdosplus, in the backwards "previous page" test. Hope all this isn't an hallucination or some grievous error on my part.....

Hi John,

I think you really should retain an older version of vDosPlus (vDos-lfn) for comparison. This way it will be much clearer if something has indeed happened to the speed and responsiveness to the more recent versions, and I will probably be able to sort things out very quickly. Without this I cannot currently really think of a particular change in recent versions that will negatively affect is speed or responsiveness (and in fact this can not be confirmed at all for now), but most likely it is simply because of some settings in your config.txt. If you are able to compare the current version with an older version of vDosPlus (vDos-lfn), it will be much easier to find out what exactly has happened.

of the most recent vdos-lfn/vdosplus versions, June 2016 vdos build. Unfortunately, I can't date it to a particular recent version.

The only older version I've retained for comparison is vdosxy3. The easiest test is paging backwards through a long document, holding down the "previous page" command, so that its repeats. The difference likely won't ruin anyone's life, but vdosxy3 is at least twice as fast (with xy3). Could be I'm mistaken, but I don't believe this was always the case(?)
