Title: Browsing Drives and Devices is slooow
Post by: ThoBar on December 10, 2009, 09:37:01 pm: Browsing drives and devices takes an age to bring up files in any particular directory...

I'm experiencing this across multiple libraries - even empty (not that it should matter), and multiple machines with different OSs.

I'm seeing the "Working... (found xxx files)" finding at best 30 files/sec on a local drive - regardless of AV status (threw that in for Jim ;) ) - by which I mean not/installed and not/enabled

Given the import routines work so much faster - what's going on? As you can imagine this is an issue when browsing directories with large numbers of files.

I'm sure you must have! :-\

Honestly, its been an ongoing issue for me, but right now (as opposed to earlier today) every machine is fine... I'm at a loss. If it reoccurs I'll let you know, but for now... :-[

[edit] Wait.... went to a folder with content MC hadn't seen before, and it's now going about the speed i initially indicated.

[edit 2] To answer the questions above....

No - and it doesnt seem to matter if its a new or old library.

What types of files?
The current folder is images, but any type is effected.

Post by: JimH on December 11, 2009, 12:10:42 pm: If a network is involved, maybe it is shifting speeds. I've read that connecting a single machine at 10Mbps can drag down network performance of all machines.

A drive that has reverted to PIO mode could also explain it.

Let us know what you find.

I sholuld point out that Explorer brings up the same files almost instantly, and fills the metadata a lot more quickly than MC.

I'll dig some more...

Post by: ThoBar on December 15, 2009, 12:04:30 am: Thanks Jim, I added the JRService to the process exception (I had already added the others), to no avail.

It seems as though if the library has not seen that folder before, thats when it takes ages. If the library has already visited the location, then it becomes quite (very) snappy - as in basically instantaneous.

I'm testing now, watching the "Working... (found xxx files)" going at about 25-40 files per second. The same folder (files imported) in another library is instant. MC is sitting between 3-15%.. AV is on 0%.

Unloading and reloading the empty library sees the same files being read in at about 250 files/sec.

To confirm: MSAV is in a non-realtime protection state, with the 3 JR processes excluded - and excluding JPG files from scanning.

BTW: I thought you were going to make a change so that you read in files, then metadata - or do I have my wires crossed?
