Igor I did SSL benchmarks with 10 worker processes on a very fast
multicore machine with multiple ssl_session_cache configs to try and
disprove this post. My results were also slow:

On a 4 core Xeon E5410 using:

ab -c 50 -n 5000

with 64 bit ubuntu 10.10 and kernel 2.6.35 I get:

For a 43 byte transparent gif image on regular HTTP:

Requests per second: 11703.19 [#/sec] (mean)

Same file via HTTPS with various ssl_session_cache params set:

ssl_session_cache shared:SSL:10m;
Requests per second: 180.13 [#/sec] (mean)

ssl_session_cache builtin:1000 shared:SSL:10m;
Requests per second: 183.53 [#/sec] (mean)

ssl_session_cache builtin:1000;
Requests per second: 182.63 [#/sec] (mean)

No ssl_session_cache:
Requests per second: 184.67 [#/sec] (mean)


I'm assuming the session cache has no effect since each 'ab' request is
a new session. But I thought I'd try it anyway.

180 per second for a machine this fast compared to 11,703 per second on
regular HTTP seems like a big difference. 'ab' was run on the local
machine (it takes very little CPU) so there was zero network latency.

Let me know if there's anything I should try to speed it up.

Here's the config I used:

worker_processes 10;
worker_rlimit_nofile 60000;
error_log logs/error.log;
pid /var/run/nginx.pid;
events {
worker_connections 10000;
}
http {
client_max_body_size 20m;
client_header_timeout 3m;
client_body_timeout 3m;
send_timeout 3m;
server_names_hash_bucket_size 128;
client_header_buffer_size 1k;
large_client_header_buffers 4 4k;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
server_tokens off;
gzip on;
gzip_min_length 1100;
gzip_buffers 4 8k;
gzip_types text/plain text/css application/x-javascript
application/javascript text/xml application/xml application/xml+rss
text/javascript;
keepalive_timeout 10 5;

proxy_next_upstream off;

geo $country {

}

include mime.types;

#the rest is basic server sections
}
