https://bz.apache.org/bugzilla/show_bug.cgi?id=62590 --- Comment #5 from William A. Rowe Jr. --- Confirmed in dev@ discussion, this flavor of ab dates to the 2.2.x epoch and is consistent for both (observed with 'This is ApacheBench, Version 2.3 <$Revision: 655654 $>'.) Because of the transition of TLS session cache to TLS session tokens, it may be worthwhile to see if this is only true of very ancient clients, and whether this combination of an older ab with an older openssl is in part to blame for the failure to speak efficiently to modern httpd linked to modern openssl. This can be tested using the most recent ab utility against both servers. -- You are receiving this mail because: You are the assignee for the bug. - To unsubscribe, e-mail: bugs-unsubscr...@httpd.apache.org For additional commands, e-mail: bugs-h...@httpd.apache.org

Rowe Jr. --- For 100% clarity, this was observed with the version of ab shipped with 2.2.34, or the version shipped with 2.4.24? It should be obvious that ab has also undergone some enhancements and changes for support of TLS, and the two different versions are expected to produce two different results. -- You are receiving this mail because: You are the assignee for the bug. - To unsubscribe, e-mail: bugs-unsubscr...@httpd.apache.org For additional commands, e-mail: bugs-h...@httpd.apache.org

--- Comment #1 from paolo ---
After some debug-session I found out that the problem are the ERR_clear_error
calls in ssl_filter_write and ssl_io_input_read. If I remove those calls the
performance is the same like with httpd/2.2.
Are those calls really needed in the ssl_io_input_read/ssl_filter_write
function?
Isn't it enough to have it only in the ssl_io_filter_handshake function.
Or what about to call this function only if an error occurred:
else /* (rc < 0) */ {
int ssl_err = SSL_get_error(inctx->filter_ctx->pssl, rc);
conn_rec *c = (conn_rec*)SSL_get_app_data(inctx->filter_ctx->pssl);
+ ERR_clear_error();
if (ssl_err == SSL_ERROR_WANT_READ) {
Many thanks for any answer.
