oePro high cpu usage

I am running OE Pro on my Intel Core 2 Duo 2,4Ghz computer. The program consumes almost 100 % of both kernels all the time when dowloading. Why does it use that much cpu? Is there something to do about it?

This simply means that your Internet connection is fast and Offline Explorer downloads Web pages at a high speed. Each Web page has to be parsed after the download - Offline Explorer finds all links, checks them against Project settings to determine if it should be followed or not. Then all links are converted for offline browsing.

Usually this consumes less CPU than 100% but if your Project settings are complex (lots of URL Filters, advanced parsing settings), it may consume 100%. In any case, this may slow down other applications, but not too critical. My experience with a simular system shows that all other applications continue to run well.

There seems to be something terrible wrong with Oe's Cpu usage. Even with all download projects stopped the cpu usage for OE.exe is around 100 %. After oe-restart the cpu usage for OE.exe seems to be normal. But after I log into the password protected site I wanna download OE.exe consumes even 50 % cpu. And that before started any downloadprojects. Mail me if you want further details.

I downloaded OE Ent. It also consumes 100 % Cpu even when there is no active download running.

I tested downloads yesterday and I found that even a very heavy download/parsing process consumes maximum 60% on my system (Core 2 Duo 2.4, 1 GB memory). I have two suggestions:

1. Please try to locate and erase URL2s.* files. Perhaps the database was corrupted and it slows down the parsing.
2. Please see the Project Properties - Advanced - extra parsing options will also slow down everything, especially scripts processing and forms exploration.

Deleting URL2s.* files didnt lower cpu usage.

The only options checked under Parsing is _Check files integrity_ and _Suppress Web site errors_.
OE.exe still consumes 95 - 100 % cpu.

The workaround is:
1. Open oe and log into site
2. Now eo.exe cpu usage is stable on 95 - 100 %
3. Make download projects
4. Close and restart Oe
5. Start the downloadprojects without enter the site in browser.
6. Now the files are downloading and cpu usage 0 - 4 %

As long as I dont enter and log into the site after oe startup the cpu usage is normal.

Can you please tell me, if any site in the Internal browser cause the high CPU load? In fact, Offline Explorer uses MS IE as the internal browser.

You are right. I logged into the site with IE. Voila! IExplorer.exe shows exactely same behaviour as oe.exe. IExplorer.exe cpu usage skyrocket to 50 % just after login. It consumses such high cpu even when IE stays "idle".

Seems like it is an IE 7 bug.

Yes, it is so.
