You are not using the WMI efficiently. You iterate over every process to
test if only one is there, when you can use WMI like so:
>>> import wmi
>>> x = wmi.WMI()
>>> x.query("SELECT * FROM Win32_Process WHERE Name = 'xchat.exe'")
[<_wmi_object: \\TOM-PC\root\cimv2:Win32_Process.Handle="7052">]
>>> def test():
t1 = time.time()
x.query("SELECT * FROM Win32_Process WHERE Name = 'xchat.exe'")
print time.time()-t1
>>> import time
>>> test()
0.0829999446869
>>>
You can further reduce load times by requesting less data from WMI, i.e
stuff you are going to use:
>>> def test():
t1 = time.time()
x.query("SELECT Handle FROM Win32_Process WHERE Name = 'xchat.exe'")
print time.time()-t1
>>> test()
0.0599999427795
