There will be some periods where the forum is unavailable, please bear with us. More details can be found in the upgrade thread.
WebIf Browse Media Files Really Slow . . .

OK: the df and df -i output both look very like mine - nothing amiss there that I can see. (You have a 2TB disk - you upgraded it yourself I guess?)
The top output: the text formatting isn't like what I get from top on my system, which is weird. (Can you tell me what version number you get when you run "top -v"? I get "procps version 3.2.8".)
The main thing though is that the processor is mostly idle. That surprises me, I admit (the stats were copied while the browser page was loading, yes?). Also, even the "io" percentage is small, so it doesn't seem to be waiting for disk accesses.
I'm out of ideas for now I'm afraid... Hopefully af123 will make something of your web-page timing info
(The one last thing I have thought of is kinda faffy - running "strace" on the httpd or jimsh processes while the request is live, to see what they're doing. It might not even work. Hence let's see what other suggestions people have beforehand!

Black Hole
May contain traces of nut
These aren't forum "rules" as such, no need to get into a lather about it, just what has developed as best practice. Rather than let newcomers find out by trial and error (and put up with an untidy forum in the process), I point them at a get-you-going guide. Simple as that, and no apology necessary.
Update: I've played around with strace and I was able to get it to work for the media browser script on my machine. It just *might* help to work out what's going on with your machine, hy4boy...(The one last thing I have thought of is kinda faffy - running "strace" on the httpd or jimsh processes while the request is live, to see what they're doing. It might not even work. Hence let's see what other suggestions people have beforehand!
Soooo, if you get bored enough
, try this:
Code:
cd /mod/webif/html/browse/
strace -tt -T -o /tmp/st.out /mod/bin/jimsh /mod/webif/html/browse/index.jim > /tmp/jimout.htmlThen you can take a look at the output file /tmp/st.out and see what you see. My file is almost 3MB in size, so probably not ideal to post it on the forum
but dropbox or similar would work - that's providing a quick inspection of the file doesn't yield any clues. NB: the start of each line will hold a timestamp for the entry point to the system call, and the last bit of each line is supposed (bit iffy in practice) to hold the duration of each call.Oops: nearly forgot - you will need to add the strace package first.

Isn't the energy of new blood wonderful.
The timing information says that it is the main index.jim script which is taking the time, but interestingly the channel icons come in after a minute so there may be an initial delay there. Have you by any chance ever enabled the test theTVDB integration feature? This tries to connect to the Internet when building the media list. You could run the tvdb/off diagnostic to be sure it's off.
Can you run the index command from the command line and see if there are any obvious pauses in the output? That will provide further clues as to where the delay is happening.
Code:
humax# cd /mod/webif/html/browse
humax# ./index.jim
.. lots of output ..
<font class=footnote>Rendered in: 1.115 seconds</font>This is definitely not related to your slow media browser.

<img src="/img/compress.png" class="va" height=21 alt="shrunk" title="Shrunk">So after a little more playing around, the 'slowness' / delays appear to be being caused by the individual recordings in the media view. I've grouped all single programs into a folder, so that now the 'My Video' directory only contains folders and it refreshes that list in about 1 second. However when I go into a folder to list the programs within, then the delay(s) reappear.

It could be that there is a problem with one or some of the files. Do you get the delinquent half-awake state? See Things Every... (click) section 18.

Divide and conquer.
I'm getting similar problems (very slow browsing of Media Library via Webif), which (also?) started after I replaced my original drive with a 2TB Seagate PVR (AV) unit. Followed the Wiki instructions for replacement, but used the native device Format option as the firmware is recent and supposed to support the 2TB units. All working OK apart from the slow browsing via the Webif and Decrypt / AutoDecrypt isn't working on recent files. One thing (maybe linked?) is that a bunch of core system (or Custom FW?) directories now appear in the "media/My Videos" directory, along with new recordings. Tempted to start over again with the disk replacement, but wonder if any better ideas? As with comments above, no strange errors showing in the logs apart from these in the Recmon log.
Device software versions are:
Web interface version: 1.2.3-5
Custom firmware version: 3.00 (build 2137)
Humax Version: 1.03.12 (kernel HDR_CFW_3.00)
df and ls -l listing of "media/My Videos" is :

You hero! Deleted all of the misplaced directories (which, as you say were also present, correctly, in /mnt/hd1) and Webif Media File Browsing browsing is now back to its old speedy self.
Also re-enabled Content Share (which had somehow become disabled) and Decrypt working again.
Many thanks for your help... So...
