Gulp imagemin压缩图片耗时过长问题求助

执行gulp images命令压缩1张及以上图片时，耗时可达2-3分钟。已尝试将gulp-imagemin降级至7.1.0版本，也调整过代码逻辑，但问题仍未解决。以下是当前使用的gulpfile.js代码及package.json配置：

gulpfile.js 代码 #

const { src, dest } = require("gulp")
const gulp = require("gulp")
const autoprefixer = require("gulp-autoprefixer")
const cssbeautify = require("gulp-cssbeautify")
const removeComments = require("gulp-strip-css-comments")
const rename = require("gulp-rename")
const sass = require("gulp-sass")(require('sass'))
const cssnano = require("gulp-cssnano")
const uglify = require("gulp-uglify")
const plumber = require("gulp-plumber")
const panini = require("panini")
const imagemin = require("gulp-imagemin")
const del = require("del")
const rigger = require("gulp-rigger")
const browserSync = require("browser-sync").create()

const srcPath = "src/"
const distPath = "dist/"

const path = {
    build: {
        html: distPath,

            }
        }))
        .pipe(removeComments())
        .pipe(rename({

    .pipe(imagemin([

        imagemin.mozjpeg({quality: 75, progressive: true}),
        imagemin.optipng({optimizationLevel: 5}),

优化建议 #

• 缩小文件匹配范围：当前images任务包含了webmanifest、xml、json等非图片文件，这些文件无需压缩，从路径规则中移除可减少不必要的处理。
• 降低优化等级：把optipng的optimizationLevel从5调低到2-3，mozjpeg可尝试降低quality值或关闭progressive选项，平衡压缩效果与速度。
• 缓存已处理文件：添加gulp-cache插件，跳过已经压缩过的图片，避免重复劳动。
• 并行处理图片：调整imagemin的concurrency参数，或结合并行任务插件，同时处理多个图片提升效率。
