Ok, thanks.
btw 'How the perf look when you use the official docker image?' - still not good. With custom image and jsreport-core - better =)

Hi. I have an issue when running reports in docker container:
On local machine rendering of pdf report with 13 pages takes ~5 sec, but inside docker container(with hole machine resources access), the same report takes ~14 sec.
JS report config:

const instance = require("jsreport-core")({
        httpPort: 3000,
        reportTimeout: 180000,
        extensions: {
          "xlsx": xlsxExtension,
          "chrome-pdf": chromePdfExtension,
          "html-to-text": htmlToTextExtension,
          express: {
            inputRequestLimit: "1000mb"
          },
          assets: {
            allowedFiles: "**/*.*",
            searchOnDiskIfNotFoundInStore: false,
            publicAccessEnabled: true
          }
        },
        templatingEngines: {
          numberOfWorkers: 4,
          strategy: "http-server"
        },
        logger: {
          console: {
            // TODO: add to the env
            transport: "console",
            level:  "debug"
          }
        }
      });
      instance.use(require('jsreport-pdf-utils')());
      instance.use(require('jsreport-handlebars')());
      instance.use(require('jsreport-chrome-pdf')());
      instance.use(require('jsreport-scripts')({}));
      await instance.init();

And docker file:

FROM node:10.17.0-jessie-slim as node-dep-installer
WORKDIR /tmp/build
COPY ./package.json package.json
COPY ./yarn.lock yarn.lock
RUN yarn install
FROM zenika/alpine-chrome:with-node
EXPOSE 9000
ENV PUPPETEER_SKIP_CHROMIUM_DOWNLOAD 1
#ENV NODE_OPTIONS --max-old-space-size=6096
COPY . /home/app
COPY --from=node-dep-installer /tmp/build/node_modules /home/app/node_modules
WORKDIR /home/app
USER root
RUN [“chmod”, “+x”, “/home/app/start.sh”]
CMD ./start.sh

Does someone have an idea what could be wrong or what can be improved ?
