High CPU load on cloud VMs

59

This weekend I benchmarked Tinc (multiple versions) on the smallest [DigitalOcean](https://www.digitalocean.com/pricing/) instance. I found that it generates very high CPU load (much more than on a desktop), and network performance...

Add TCP_QUICKACK setting

4

See the commit messages for details. I could run the normal tests, but not the mock tests since they don't compile on #master (see #65). Related downstream PR: https://github.com/serokell/network-transport-tcp/pull/1

TCP_NODELAY=True would be a better default

1

network-transport-tcp has `tcpNoDelay = False` by default. Enabling Nagle's algorithm (not setting `TCP_NODELAY`) is not appropriate for cases where many multithreaded users multiplex over a single TCP connection, as is...

Allow rtsps URLs

2

Hi, thanks for this nice app. Gstreamer also allows `rtsps` URLs (RTSP over a secure TLS connection), but your client forbids those [here](https://github.com/otonchev/rtspviewersf/blob/e57923e29b02216004024ac584cf3cf5beb871da/src/com/gst_sdk_tutorials/rtspviewersf/ConfigurationManager.java#L273). Could you make another version that does...

Random generation is very slow

6

For testing my binding to the `lz4` compression library (https://github.com/nh2/lz4-frame-conduit), I need to generate a lot of large `ByteString`s. Unfortunately I can barely use quickcheck for this, because its random...

Clarify how `zstyle -T ':grml:chpwd:dirstack'` is supposed to be set

1

For most `zstyles`, I can set them any time and then they apply. But in https://github.com/grml/grml-etc-core/commit/d005e0b78bac79a566a3b16fb9e66b28bca48d61, the `if zstyle -T ':grml:chpwd:dirstack' enable` is on the top-level of `.zshrc`, so it...

Assertions not triggering with -O and test suite failure

2

Hi, version `0.11.4.16`. When you test with `./Setup build test:test-evp-base64 --ghc-option=-O0` or in `ghci`, then a test failure occurs (I've inserted some more stack traces and prints for your convenience):...

srtp/gnutls aren't included in gst-build, which makes it hard to build the demos with meson

13

Hey, thanks for your work on this. Could you make the running instructions a bit more concrete? E.g. how to precisely continue after having built gstreamer with `gst-build`. I've built...
