The lag seem to occur when the channel nick listboxes are being filled. Overall there is much more lag when receiving server responses (e.g. services notices or from a whois) in my case, which is probably a reason for the above. Edit: ok, I just did some benchmarks to get actual numbers. v7.12 vs v6.35, both copies connected to the same server and (SSL) port, with the same set of (simple) script files loaded. 20 PINGs sent to the server with $ticks (//.quote PING $ticks), alternating between both mIRC copies to try and eliminate temporary server-sided lag. With the help of /debug, the difference was calculated between the value of $ticks when sent and the value of $ticks at receiving the server reply. Highest and lowest differences in ticks crossed out and the average of the remaining 18 taken. v6.35 : 177 ticks v7.12 : 907 ticks Last edited by Khaled; 12/10/10 03:49 PM.

I'm just wondering if it might be related at all to SSL because I haven't really noticed a difference in speed connecting. Of course, I also am not in many channels and usually am not paying much attention while connecting anyhow. Last edited by Khaled; 12/10/10 03:49 PM. Invision Support #Invision on irc.irchighway.net

I believe the same holds true for a non-SSL connection though, but I'll have to back that up with numbers. Last edited by Khaled; 12/10/10 03:50 PM.

FYI: I have tried this with both the Win32 OpenSSL v0.9.8o and the Win32 OpenSSL v0.9.8h binaries with the same result. Last edited by Khaled; 12/10/10 03:50 PM.

Khaled Hoopy frood Joined: Dec 2002 Posts: 5,482 London, UK	Thanks, I was able to reproduce this issue. It is due to a change that fixes a bug in previous versions of mIRC that caused SSL connections to occasionally freeze mIRC when many SSL connections were open. I think I may have mentioned this in a previous post. I am leaving this change in place for the moment but may look at it again in the future.
