I'm sending a message with about ~150k repeated items in it, total
size is about 3.3mb, and its taking me about 100ms to serialize it and
send it out.
Can I expect to do any better than this? What could I look into to
improve this?
- I have "option optimize_for = SPEED;" set in my proto file
- I'm compiling with -O3
- I'm sending my message in batches of 1000
- I'm using C++, on ubuntu, x64
- I'm testing all on one machine (e.g. client and server are on one
machine)
My message looks like:
message NodeWithNeighbors
{
required Id nodeId = 1;
repeated IdConfidence neighbors = 2;
}
message GetNeighborsResponse
{
repeated NodeWithNeighbors nodesWithNeighbors = 1;
}
message IdConfidence
{
required bytes id = 1;
required float confidence = 2;
}
Where "bytes id" is used to send 16byte IDs (uuids).
I'm writing each message (batch) out like this:
CodedOutputStream codedOutputStream(&m_ProtoBufStream);
// Write out the size of the message
codedOutputStream.WriteVarint32(message.ByteSize());
// Ask the message to serialize itself to our stream adapter, which
ultimately calls Write on us
// which we then call Write on our composed stream
message.SerializeWithCachedSizes(&codedOutputStream);
In my stream implementation I'm buffering every 16kb, and calling send
on the socket once i have 16kb.
Thanks!
