#10 Process priority

[Tomek]

Please change default priority of indexing process to
Idle.
Moreover indexing should stop, when I close explorer
window or should index files slower, there should be
option to set max index speed, it takes too many
resources.

I think what you mean is lower the priority of the indexing
THREADS. This may be a good idea, but there may be some
priority inversion issues that I'd want to look into first.

The indexing already does stop when you close Explorer
windows, after it's finished scanning once everything you've
looked at in Explorer. So next time you open Explorer, it's
already got it. But it won't keep scanning after the first
scan if there are no Explorer windows open. This behaviour
is by design.

Also, the scanning already doesn't run at max speed. It
keeps your disk bandwidth below a threshold. When other
applications use disk resources past this threshold, the
scanner stops entirely. Since this system was implemented, I
haven't noticed significant slowdown.

Please respond if you can be more specific about how much
slowdown you're experiencing while the service is scanning.

For example, when I open root directory of C:\ whole drive
is counted, it takes very many resources. When I try to run
Word, it starts about 37s, when system is idle, it takes no
more than 4s. My HDD can read about 35-40MB/s. C:\
partition has 19GB, and about 16GB is used.

I think, you should add speed limit option to config file.
No special interface for configuration, only one config
file will be enough for me.

Wow, that is a big performance problem! Thanks for the
detailed information.

I was seeing some pretty bad slowdowns too before
implementing the system to stop scanning when other
applications are using the disk. It sounds like this isn't
functioning for you. Are you using Folder Size 2.3? If not,
please upgrade and hopefully this will improve
significantly. If this doesn't help, please email me so I
can address this problem in the future.

Thanks.

Use less memory for the cache (or make maxmem an option), I
currently have > 100MB for FolderSizeSvc.exe (release 2.3).
