I also have Rapport Trusteer installed from BoA with Firefox and have 
not had the problem when using it. On the other hand in my case I may 
have discovered a connection with Softerra laimex command line utility. 
A script which uses it on a desktop has the slowness issue whenever the 
script is run (after sqlcmd and laimex has completed, the issues surface 
for the rest of the script). I was unable to set up my script on a 
laptop in part due to the need of the use of a VPN and because the IP 
addresses I was given were not "private" (for unknown reasons as it 
should have worked either way just like on my desktop that had the 
slowness issue). Once I replaced all of them with the "private" one's I 
was given, laimex worked to get the data I needed. A week later (today), 
I check the PC that was giving me problems and it was running smoothly 
without the issue happening and this coincided with me updating my 
config file with the updated IP addresses. There are still some puzzling 
things, like why this all started after an update to Cygwin. What I need 
to do now is to set up a test config file with the old addresses and see 
if I am forced to reboot the desktop due to the slowness. The thing is 
that when running Softerra LDAP Administrator and getting data through 
the GUI, it was never an issue.
