Is opening slow for every topic even if you import only a single one? How large is a single HTM file? It may be that opening is not related to the number of topics but to how large each topic is. If you have very large topics, it may take some time for RH to load them and show them in the editor.
Is RH also slow apart from opening the topics? Such as creating new topics, closing the project, opening the project, etc.?
The files range from 20kb to 300 kb
A 20 kb file takes about 15 sec to open, a 150 kb file takes about 30 sec.
This is on a Win 7 machine, Intel i7 w/ 8GB memory. So it has reasonable compute speed, and shouldn't be slowed by lack of memory.
The project opens quickly. I don't use RH much, having to re-learn what little I did know.
if the use of this strangely-sourced HTML doesn't sound like a huge issue, I'll continue and see how it goes.
I should note that there aren't any calculations in the files - these are instructional documents that happened to be created in Excel.
Where is the project? Is it on your local C drive or is it on a network drive?
If it's on a LAN drive, try closing the project, copying it to your C drive (perhaps to a location such as C:\Projects\ProjectNameHere) and see if your speed has improved.
thanks - I should have mentioned - it is on a local drive.
the drive has 384GB free.
So, free space should not be the issue, nor network latency.
