Re: Poplar Proxies don't reach 3 meg speed
The verdict of SG's analyzer (if you allow the transparent proxy, it reads YOU, if you force-proxy, it reads the proxy) is not 100%

Quote:
Default Receive Window (RWIN) = 70080
RWIN Scaling (RFC1323) = 1 bits (scale factor of 2)
Unscaled Receive Window = 35040
RWIN is not fully optimized (even though it is a comparatively large number). The unscaled RWIN value is lower than it should be. Also, RWIN being close to and above 65535 does not justify the header overhead of enabling TCP Options. You might want to use one of the recommended RWIN values below.

RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)
