With SLA, timeout is in milliseconds, so if you put frequency 1 and timeout
10
you probably mean
R1(config-sla-monitor-echo)#frequency 1
R1(config-sla-monitor-echo)#timeout 10000
%Illegal Value: Cannot set Timeout to be greater than Frequency
Also, for TCP connect, you basically just test connection timing. If you
need
to simulate really heavy TCP flow, run FTP client and FTP server on IOS :)
[Or copy files via HTTP, if you need something more strightforward.]
Anyway, IOS supports FTP/HTTP GET as SLA operation.

R1(config-sla-monitor)#type ftp operation get url ftp://1.1.1.1/ios-image
