I want to use CGWatcher, but I find that I get a much lower hashrate when I start cgminer from CGWatcher than from a batch file.

Example batch file:

ECHO This is "GPU mining.bat".
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

cgminer --config mdl.conf

pause
exit
===============
Example config file = mdl.conf:

{
"pools" : [
   {   "url" : "stratm+tcp://middlecoin.com:3333",
      "user" : "redacted",
      "pass" : "redacted"
   },
   {   "url" : "stratum+tcp://ltc.give-me-coins.com:3334",
      "user" : "redacted",
      "pass" : "redacted"
   }
   ],
"usb" : ":0",
"scrypt" : true,
"gpu-platform" : "1",
"thread-concurrency" : "21712",
"auto-fan" : true,
"auto-gpu" : true,
"gpu-engine" : "900-1150",
"temp-target" : "80",
"temp-overheat" : "90",
"temp-cutoff" : "95","intensity" : "13",
"worksize" : "256",
"api-listen" : true,
"api-allow" : "W: 127.0.0.1"
}
============

(The same problem also happens with a different config using a single pool.)

I am using cgminer v. 3.6.6, CGWatcher 1.3.3.2, Windows 7 Pro 64 bit SP 1. When cgminer is already running and I start up CGWatcher, it monitors okay and does not affect the hash rate. When starting from the batch file, both cgminer and CGWatcher report a hash rate around 560 Kh/s. When starting or restarting from CGWatcher, I usually get 5 to 20 Kh/s, although once I got in the 450 range.

I hate to report the same problem someone else did, but in a comment at http://manotechnology.blogspot.com/p/cgwatcher.html, Tomá Bräuer on August 14, 2013, reported his rate dropping from around 800 Kh/s to 620 Kh/s under the same circumstances. Unfortunately, for some reason I can't load the next page of comments from that website to see what he was told.

One oddity is that when monitoring, CGWatcher reports:
[12/9/2013 4:35:05 PM] -- Begin CGWatcher v1.3.3.2 Process -------------------------------------------------------
[12/9/2013 4:35:09 PM] Running miner detected: CGMiner using "NEW Fastcoin" profile.
[12/9/2013 4:35:09 PM] Active profile is "NEW Fastcoin"
[12/9/2013 4:35:09 PM] CGMiner instance found.
[12/9/2013 4:35:09 PM] The current running miner's profile is "NEW Fastcoin".
[12/9/2013 4:35:10 PM] Monitoring is turned on at 30 second intervals.
====================
. . . and "NEW Fastcoin" profile points to a different pool than the one cgminer is using.

After collecting the log above, I paused and then resumed mining and it came up with the Fastcoin config, running at a 10 Kh/s rate. I then checked the "Show debug log entries" box, paused and restarted cgminer, and the new rate is about 430 Kh/s (vs over 500 when starting from the batch file).

The whole log now reads as follows:

=================

Some of the ignored miner instances mentioned in the log may refer to the fact that I have cgminer-nogpu running some bit erupters in another task. That task has seemingly been unaffected by all this.

Any comments/suggestions from milone or anyone else?
