...OS X, it works great, adding only about 20% extra latency into the connection when proxying versus connecting to the original backend process directly, so a 5ms connection might now take 6ms. On a Linux deployment, however, that 5ms was going up to 150ms! I noticed that when I removed EventMachine.epoll, everything corrected itself and it worked as quickly as in OS X. So, for now I''ve removed EventMachine.epoll, and all is well. The first question, therefore, is does anyone have any experience or knowledge of why using epoll could make an EventMachine daemon work more slowly? Note that...

...(kernel 2.6.9-55.0.2.plus.c4) with a ruby-1.8.5 RPM from the CentOS testing repository. When I run it, I find that set_comm_inactivity_timeout doesn''t do anything. That is, if I client opens a connection, it stays open indefinitely. However, if I comment out the line "EventMachine::epoll" then the problem goes away, and timeouts start working. Is this a known issue with epoll? The ''EPOLL'' readme file doesn''t seem to mention it. Regards, Brian. -- 8< --------- require ''rubygems'' require ''eventmachine'' modul...

Hello, As part of the Rust bindings for Libnbd, I try to integrate the asynchronous (aio_*) functions with Tokio <https://docs.rs/tokio/latest/tokio/>, the most used asynchronous runtime in Rust. However, in its eventloop, Tokio uses epoll(7) instead of poll(2) (which is used internally in Libnbd). The difference is that poll(2) uses level-triggered notifications as aposed to epoll(7) which uses edge-triggered notifications. In short, the difference is that if one would wait for a file discriptor to be readable, epoll would bloc...

Hello, this patch adds ioloop handler using Linux 2.6 epoll API. I'm not sure is it ready for inclusion right now, but it works for me and survives deadconn test with 1024 simultaneous connections.

I am running dovecot 1.0 beta3 as a front-end proxy, and getting the following error when using epoll. The error goes away if I switch to poll.

Francis, I read in the list archives back that a future EventMachine release will support epoll on Linux (i.e., it''s in the trunk). Better still, is there a possibility that EM will rely on libevent so that it will be architecture independent (i.e. epoll on Linux, kqueue on FreeBSD/Mac OS X, /dev/poll on Solaris)? This is how memcached is implemented, and it would be helpful to be...

Guys, Just for fun, I tried to see (I know, a silly way to test it) how much overhead we have calling the C functions of the extensions. the benchmark script and the results: http://pastie.caboo.se/128646 The naive C extension: http://pastie.caboo.se/128647 I compared 1.8.6 (VC6 and mingw builds) against a fresh checkout of ruby trunk. What I understand from that is 1.9 is slower than 1.8

I know this error has been reported before, but a couple ppl have reported getting this randomly when running Thin and it crashed the server: terminate called after throwing an instance of ''std::runtime_error'' what(): unable to delete epoll event: Bad file descriptor I think it''s fixed on trunk now so I''m telling people that have this issue to checkout and install EM from trunk. It seems to be a pretty important issue so I''m wondering when is 0.11 being pushed to rubyforge? thx, Marc -------------- next p...
