Msg: Re: speed of vdosplus

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(?)
