Not all websites support persistent connections and, some of those that do, do not keep connections open long enough (e.g. HTTP(S) persistent connections support is now available in IBrowse 2.5.3 (can be disabled in the settings). However, it can be useful for HTTPS connections as it allows them to be left open and reused, without having spend CPU time renegotiating the SSL connection at all.
This is an older HTTP feature that was never implemented in IBrowse until now, partly because IBrowse has always relied on opening multiple connections to websites, which didn’t really make this feature worthwhile. Most websites support this feature universally. This allows the slow initial handshaking to be bypassed on subsequent connections to the same host, thus increasing performance noticably on OS3, and even on OS4 too. IBrowse 2.5.3 now implements a SSL session cache for all HTTPS connections, supporting all the differing session/ticket methods use from TLSv1.0 to TLSv1.3. Therefore, some other options have been exploited to enhance performance, which have been in beta testing over the past 3 months, due to the major changes required to the HTTP engine… Despite the performance enhancements that came in AmiSSL 4.4 (4.6 is available now, by the way), there is not much more that can be done in AmiSSL unless someone is able to write 68k assembly optimised versions of some of the modules (as is the case for PowerPC). The main target for this new version was to improve performance on HTTPS connections, given that SSL is relatively slow on 68k processors.
We hope you are all well in these strange times – stay safe! IBrowse 2.4 and 1.x users can upgrade to IBrowse 2.5.3 via our store at discounted rates.
