€18-36 EUR / hour

Looking for an experienced Linux Expert / Professional. You must be skilled in QEMU/KVM virtualization, debugging and monitoring. Since we already tried a lot and where not able to slove this issue. Required Experience - Linux Expert / Professional since several years (preferably Fedora/RHEL) - Skilled in Virtualization on Linux (QEMU/KVM) - Able to debug / monitor on Linux to spot the issue - Good with new hardware (especially AMD) - Good english skills for clear communication. What we provide You get direct access to this workstation (thru teamviewer). Its state of the art with following components: - AMD Threadripper 2990WX 32Core CPU running @ 4.2GHz on all cores - 128GB RAM running at 2966 MHz CL14 - 4x Intel Optane NVMe Drives in a RAID0 - Dual 2080Ti NVLink Nvidia Card, 10GBit Network Card - The system has a 1GBit UP/DOWN Link with good international peering so it will be good remote working. The issue This workstation will be used for virtualization testings of many VMs (Windows / RHEL / CentOS / Fedora Server / FreeBSD etc.) at the same time. Currently we are not able to get decent performance on the Windows VMs. They run very sluggish and slow. It seams like you are connected thru a 56k modem to this VMs. Ubuntu and Fedora test VMs run flawlessly.

"why we should choose you": +20 years working in unix/linux performance and problem finding, most HP-UX and linux, for HP Mexico and USA. Many years with unix/linux experience, C programming, etc. Oracle OVM admininistrator, and performance (QEMU based) "WHY NOT": - experience in windows :( Tips: First find the problem, then fix it. You seams to don't know where is the performance problem, lets start there: 1) Is the windows cpu slow, some benchmark for windows cpu, best is it is character based, no window based 2) I/O to disk 3) Network 4) Console What is the windows version? what do performance tools inside windows show?

Hi, I'm a Linux System administrator with lots of experience regarding Virtualization (including your exact setup) and I have successfully resolved countless performances tunes and strange edge cases. Now from the way you talk and the level of details provided I assume you are a professional also. I read about your problem and I believe I might have the clue as what causes the problem (Virtio network driver is at fault, it needs a very specific configuration sometimes). Here's the deal, I don't think your proposal of charging an hourly rate is good for this, my offer is that you award the project to me and **if** I could fix the problem then I would provide the documentation and explanation and everything you need or if you prefer via TeamViewer, I'd be more than happy to assist and help you understand the way I solved it. The thing is no matter how many hours I actually spend I charge 350 equals 10 hours of work, and if I couldn't no matter how many hours I spend you don't pay me anything :-) I can start on your project immediately and let me know if you want to discuss anything further with me. Thanks.

Hello there, I am a scalable microservices developer with JHipster primarily using Docker/Docker Compose and the Netflix OSS stack (Eureka, Zuul, Hystrix), and also utilizing other industry best practices and standards such as JWT security, rate limiting, WebSockets, ELK (Elasticsearch-Logstash-Kibana), and API-first development with Swagger/OpenAPI, to name a few: Currently I am also checking out a new, modern Java cloud-native microservices framework that is very fast and lightweight, just like Go (Golang). Banking, fintech, e-commerce, and blockchains/cryptocurrencies are only some of my core domains having worked with various banks, financial institutions, e-commerce service providers, and blockchain projects. I have just finished a stint as a Java/Go Web e-commerce ERP/CRM developer for an Austrian company and I am looking for new and preferably long term opportunities. I have had already delivered many successful projects since starting full time freelance work three years ago. Please see my profile for the rest of my portfolio, work history, and qualifications. I am well-versed in both SQL and LDAP databases; my NoSQL experience is with Apache Cassandra and MongoDB. My frontend JavaScript stacks are Angular 2+, Google Polymer, and React. My cloud platforms are AWS and Heroku but I can also handle others. My Java EE middleware production experience is with Oracle WebLogic, JBoss/Wildfly, and Apache Tomcat; also an expert with Jetty. Best Regards Thank you.
