Nagles (not Nangles) is the TCP_NODELAY option.

However, simply showing how many packets have come and gone shows NOTHING about the performance.

Have you tried using a tool to actually gauge performance and throughput?

Also, how come you are not using the bnx2 driver?

CURLOPT_TCP_NODELAY(3)					     curl_easy_setopt options					    CURLOPT_TCP_NODELAY(3)

NAME
CURLOPT_TCP_NODELAY - set the TCP_NODELAY option SYNOPSIS
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TCP_NODELAY, long nodelay); DESCRIPTION
Pass a long specifying whether the TCP_NODELAY option is to be set or cleared (1 = set, 0 = clear). The option is set by default. This will have no effect after the connection has been established. Setting this option will disable TCP's Nagle algorithm. The purpose of this algorithm is to try to minimize the number of small packets on the network (where "small packets" means TCP segments less than the Maximum Segment Size (MSS) for the network). Maximizing the amount of data sent per TCP segment is good because it amortizes the overhead of the send. However, in some cases small seg- ments may need to be sent without delay. This is less efficient than sending larger amounts of data at a time, and can contribute to con- gestion on the network if overdone. DEFAULT
