Hi everybody!

Pre-2.52 is here for your tests. This build fixes a few issues, but he most important here is CPU usage by periodical check functions.

www.softsphere.com/files/DefenseWall_HIPS_v2_52.exe

The build is updated.

Here is DW's last build CPU usage (Win Pro sp2, "Periodically check applications from built-in list" and "Show logs" are not activated), if it could help:

here is to much cpu usage(spraking) in short time , like defesewall seeking for something ... i am talking about 0 - 25 cpu use...

To be honest - i didn't noticed any changes in CPU usage/time in my case it looks the same as in previous version.
Process Lasso after ~3-4h browsing shows average CPU usage = ~3%
CPU Time in Windows Task Manager = ~12min

try look in windows task manger at "defensewall.exe" and tell to what high does the cpu sparks goes... and for how long

Creer, how does your 12 minutes compare to other applications?

Just started testing pre-2.52 and I can see a BIG improvement in CPU use. CPU time is now back down to what it was in Defensewall several versions ago.

max value is ~10%

Current results- after ~5-6h - From higher:
Opera Browser: ~43min
defensewall.exe: ~16min
explorer: ~12min
System: ~11min
Online Armor 1#process: ~4min
Online Armor 2#process: ~3,5min

Here are mines, after about 5 hrs:

DefenseWall .... 36 min
K-Meleon ........ 27 min
System ........... 13 min
Proxomitron ..... 10 min
Explorer ............ 8 min
csrss.exe ........... 2.5 min

seems defensewall 2.52 suck 2 much cpu power as i claim before. its interfere with games and surely slow down browsing, and other pc tasks

So, do you have any improvements with the latest build?

The highest cpu peaks have lowered a bit, but the other numbers stay about the same here (see the graph pict in the post #3 in this thread).

ilya i dont understand why DW need to use some much cpu so often , even if it check like u said before that all programs are untrusted... look little odd to me ...

It checks:
1. Resource protection list.
2. Built-in untrusted list.

If you still have a huge CPU spikes, you have to contact me via support e-mail I could send you test executables back to profile the problem sections.

i gave DW a night test(didn't touch the pc) , with 9 process under it , firefox was open , a bout 9 sites open ,Periodically check applications was checked also , and here are the results

system idle process 7:12:31
defensewall.exe 0:58:45
firefox.exe :0:29:33
system 0:11:18
explorer 0:4:57

i use winxp sp3 + DW 2.52 , its seems this build even it use lots cpu requests, it doesn't slow or interfere with pc speed much or what so ever...

There is a big difference between CPU requests and CPU usage. Naturally, DW do a lot of requests as it displaying a status at title bars with its main GUI module, without injecting additional modules into the processes. But, one more time- if it do not disrupts your regular work/gaming, it's all OK.

So, my main concern is about CPU usage.

gaming is running OK , so i assume this issue is coming to his end (for now :) )

Max value of CPU usage which i have noticed was ~10% but i don't look still on Windows Task Manager so maybe sometimes it is higher i don't know. BTW is there any software which could tell me about the highest level (in this case) CPU usage selected process/application running on my system?

I must say this beta of 2.52 is running very smooth/light on my system. I hardly notice that it's even there. Nice.

Question. My wife and I are planning on going to the beach this summer. I assume there will be wireless public access points. My question....will the selection under Options titled "Run from local area network sources as untrusted" protect our notebook?

Thanks for any info on this.

Later....

If you are not going to use that local network resources- no, it won't helps. But a well-tuned inbound packet firewall and using strong security (at least WPA, WPA2 is the best choice, WEP is crap) access points can.

Firewall and using VPN is best protection...public WIFI is risky.

The build is just updated.

ilya what have been update? its says 2.52

I've installed pre-2.52 v. and want to notice, that this version uses less CPU (the average CPU usage is less than when there was v. 2.51 installed). But perhaps I'm wrong.

They all are 2.52, but the builds are different.

yes but there are changing , and it alwas 2.52 ....not like 2.51.1...2.51.2...2.52.2 etc

Ilya could the CPU usage be caused by the contineous sending of text messages to secured applications (to show DW in the window header)

Interesting thought Kees, however I note that Sandboxie also amends the window header with a couple of [#]s but doesn't have a CPU issue.

I've run a quick experiment. I disabled resource protection and check built in list and rebooted. Even with no untrusted applications running DW is taking up CPU every now and then. I'm not saying it's a problem for me, I'm just curious as to what DW is actually doing to be eating CPU cycles when no untrusted apps are running and resource protection and built in list are disabled.

ilya about this cpu uses , this way or another it is using it/eating it more than all other software protection i got , actually more than all of them together.

my question goes for if i disable periodically check , can it reduce the cpu uses?
and does i loose protection coz of this disable? is it critical?

ps: last build i d/l again freezes my games time 2 time even periodically check unchecked
10x

The CPU usage has lowered by much (about half of what it was) with the very last build here (after 2 hours of monitoring).

EDIT: Oops, it seems I talk too early, it seem to be returned now to what it was :(

(see screenshot)

so its maybe aint enough , duno , other hips i used and test never encore such a dramatic CPU use .

Hi Ruinebob-Inn,

What software you used for these nice processes/CPU graphics ?

CPU time usage- yes, CPU spikes- no.

Anvir Task Manager Pro for CPU monitoring, and SnagIt for snapshots/anotations.

So how does Sandboxie, which also skins the sandboxed program with additional text, get round this and show virtually no CPU time usage?

big question , hope ilya can answered it

Finally, I booted on a pretty clean and patched win pro sp2 snapshot , and installed DW+Anvir+SnagIt. So this should give a good baseline picture of DefenseWall's CPU used for me.

see the resulting graph.

what do u mean by "patched win" ? with tweeks?

Only Microsoft security patches for Windows XP Pro SP2.

i will post my 2 same anvir software scale

it uses 47% of my cpu :(


sometimes its 65%

Yes, it's not normal. Looks like something is wrong. Please, check the latest pre-2.52 build I just uploaded.

ilya remove old one and than installl?

so files be update and no leftover left...am i right?

Install overtop and reboot.

i uninstalled (keep setting) and install .... will give anvir some times to sample defensewall.exe cpu thing

Aha, and don't forget to check if "remote assistance" feature works.

I'm seeing further CPU improvement with this latest build, but what the hell is going on with disk usage in my screen capture????

Is that reads or writes?
