17:44:53  <kellabyte>bnoordhuis: how do I send data with libuv so that it sends with larger packets?
17:45:17  <kellabyte>bnoordhuis: I see some apps on this server sending 8KB packets (I think) but mine is only sending 1.3KB ones it looks like
17:45:56  <kellabyte>bnoordhuis: I've used uv_write() and uv_try_write() to batch multiple buffers, it seems to reduce syscalls but not seeing as significant of a throughput improvement

18:33:02  <rendar>kellabyte: it depends on the operating system
18:33:34  <rendar>kellabyte: i think from user mode you can only grow the per-socket kernel buffer (that is, skbuf in linux or mbuf in bsd*)
18:34:05  <rendar>with some fnctl or something
18:37:10  <kellabyte>rendar: hmm ok, just wondering how redis and iperf are doing 2GB/s but can't seem to get past 1.4GB/s in my libuv app
18:37:20  <kellabyte>even if I run multiple instances, its sending way more packets but smaller

18:46:42  <rendar>kellabyte: hmm, redis is doing 2GB/s?
18:46:59  <rendar>kellabyte: you mean in your local machine? in loopback?
18:51:16  * amurzeaujoined
18:55:40  <kellabyte>no, between 2 benchmark machines
18:55:48  <kellabyte>the same one I'm benchmarking against for my app
18:55:56  <kellabyte>so its not an OS difference, its not a loopback, its bonded 10GbE
19:02:17  <amurzeau>libuv application use 100% cpu on one core ?
19:08:54  <kellabyte>doesn't matter, even if I run N instances per core it won't go any more throughput
19:09:05  <kellabyte>its sending 1.3KB packets and the others are sending 8KB
19:15:33  <amurzeau>what's the buffer size you pass to uv_write ? iperf does 128kb writes
19:17:59  <amurzeau>(I meant 128 KBytes not kbits)
19:35:29  <kellabyte>I've tried sending larger buffers and seems to make a bit of difference but not nearly as much
19:35:41  <kellabyte>it feels like I'm benefitting from syscall reduction more than packet size
19:35:51  <kellabyte>I don't see an increase in packet size as far as I can tell
