Re: speed of vdosplus

["John Paines" <dmarc-noreply@xxxxxxxx>]

If anyone is still following this issue, the cause appears to be the keyinter and keydelay settings,
which adversely performance on some (but not all) repetitive functions. Â How I overlooked
the matter, I don't know....

In this case, with the keyboard settings active (for faster cursor movement), there was no
significant difference between vDosPlus and the earlier vdos-lfn version when holding down PgUp and
moving backwards through a long document, as Wengier noted. Â But holding down alt+PgUp
(previous page command) did result in uneven and slowed performance on vDosPLus. Â Remove
those key control settings, and performance is effectivly the same between the two versions on both
tests.

The all-time champ on these tests is vdosxy3 (*with* faster keyboard settings active), though we're
talking about a 2-3 second advantage when moving through an 178 page document.

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). Â 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. Â 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.

 Wengier,

Hate to sound thankless, but I think something has happened to the speed and responsivenessof the
most recent vdos-lfn/vdosplus versions, June 2016 vdos build. Â Unfortunately, I can't
date it to a particular recent version.

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