Nick Apperson	ee95e4f5f7	buffer: improve {read,write}{U}Int* methods Increase the performance and simplify the logic of Buffer#write{U}Int* and Buffer#read{U}Int* methods by placing the byte manipulation code directly inline. Also improve the speed of buffer-write benchmarks by creating a new call directly to each method by using Function() instead of calling by buff[fn].

Ben Noordhuis	8ae32a9864	bench: fix buffers/buffer-base64-encode benchmark The test is supposed to measure the performance of the base64 encoder so move the Buffer#write() calls out of the benchmark section. The overhead of the calls isn't terrible (about 1-3%) but having unrelated activity in a micro-benchmark is never a good idea. Signed-off-by: Trevor Norris <trev.norris@gmail.com>	11 years ago

Raymond Feng	4c672c8a5e	benchmark: Add a test to measure Buffer.slice perf Buffer.slice can be expensive. One regression was reported by https://github.com/joyent/node/issues/7633. The method should be benchmarked.	11 years ago
Sean McArthur	226f98a356	buffer: add compare and equals methods compare() works like String.localeCompare such that: Buffer.compare(a, b) === a.compare(b); equals() does a native check to see if two buffers are equal. Signed-off-by: Trevor Norris <trev.norris@gmail.com>	11 years ago

Trevor Norris	22668db73d	benchmark: update callbacks only receive data Since the SlabAllocator was removed the buffer length/offset is no longer sent to the onread callback. The benchmarks have been updated to reflect that.	11 years ago
Ben Noordhuis	fda2b319dc	http: save roundtrips, convert buffers to strings This commit adds an optimization to the HTTP client that makes it possible to: * Pack the headers and the first chunk of the request body into a single write(). * Pack the chunk header and the chunk itself into a single write(). Because only one write() system call is issued instead of several, the chances of data ending up in a single TCP packet are phenomenally higher: the benchmark with `type=buf size=32` jumps from 50 req/s to 7,500 req/s, a 150-fold increase. This commit removes the check from `e4b716ef` that pushes binary encoded strings into the slow path. The commit log mentions that: We were assuming that any string can be concatenated safely to CRLF. However, for hex, base64, or binary encoded writes, this is not the case, and results in sending the incorrect response. For hex and base64 strings that's certainly true but binary strings are 'das Ding an sich': string.length is the same before and after decoding. Fixes #5528.	12 years ago

Trevor Norris	31314b6978	bench: compare binaries equal times The benchmark compare would drop the last run of the binary pairs. So when they were only run once an error would arise because no data was generated for the second binary.	12 years ago

isaacs	d62cf59dc1	http: Don't hot-path end() for large buffers The benefits of the hot-path optimization below start to fall off when the buffer size gets up near 128KB, because the cost of the copy is more than the cost of the extra write() call. Switch to the write/end method at that point. Heuristics and magic numbers are awful, but slow http responses are worse. Fix #4975	12 years ago

isaacs	db5d58e842	bench: Use environ to run compares more than once This will run the benchmarks the number of times specified by NODE_BENCH_RUNS, to attempt to reduce variability. If the number of runs is high enough, it'll also throw out the top and bottom quartiles, since that's where the outliers will be. It's not very fancy statistics-fu, but it's better than nothing. Also, linted this file. It had tabs in it. TABS!	12 years ago
