We have a bash script with several regular expression written with awk, sed and grep in Linux. Script is quite slow and it necessary to speed up processing. Script is like: sed 's/a/b/g' file | sed 's/c/d/g' | ... with thousand of pipes, but same type of expression. We need a freelancer to improve speed, reduce I/O and make a portable software in C or C++. There are some libraries in C and C++ and we need someone that can really optimize software. It will be a plus if software can run in Linux and Windows. Documentation, source code and instructions how to compile software is a must.

Hi! I have done many scripts to C conversions, so I can solve this task fast and with high quality. Also I skilled with cross-platform applications. Source code will compile and work on both required platforms with same speed. If you interested you can give me some portion of this or other processing script and I produce demo for you.

I believe the largest speedup that can be achieved here is to combine the pipeline into a single program. For this reason, I propose to create a pipeline mechanism based on C++ templates with stages for the common pipeline elements being implemented in discrete classes. I've just got off another job where I optimised a string search function using the SSE4.2 asm instructions, so I'd be interested to see if I can use that technique here as well, but such an investigation will come after the main structure implementation. Thank you, Daniel Horne

I have been working as a ETL developer immediate after my graduation until now. I do this kind of tuning for many times and I am fond of doing so. I cannot told you how can I enhance the performance until I could have a look on the bash script and the sample file, but I will make it work.
