I have just posted r41Beta5 to the MagmaTester project of squeaksource.
Testing on slow networks has revealed compression can make a significant improvement! However, compressing *everything* can be wasteful for very small ByteArray's. The lz compression adds a 20-byte header, so it is really wasteful with tiny requests/responses for both computers to go through compression/decompression cost while INCREASING the number of bytes to send over the network.
So I went ahead and chose an arbitrary threshold of 200 bytes. Any request/response over 200 bytes will be compressed. This threshold can be tweaked if necessary, but the benchmark results are really good compared to all-compression or no-compression. Magma now basically maintains the framework-oscillation rate at the high level we get on fast networks, while still providing exceptional benefit for slow networks.
Also available is a new version of Magma Tools. There are several improvements to the benchmarker.
- Now reporting totals for MagmaBenchmarker. Also including the Client Session Statistics Report, subtotaled by benchmark test! - Also included is the Server Statistics Report. - The statistics report also now includes versions of *all* packages instead of just MagmaTester. - Now disconnecting the session after running the test!
The cumulative performance enhancements for r41 are starting to accumulate into a significant overall improvement!
Enjoy, Chris
